Thunderstorm Phobia #2

There are at least three reasons a dog may become fearful during a thunderstorm.

 

Because these factors may be intertwined, owners of fearful dogs are encouraged to try a variety of techniques; when needed under the guidance and with the support of a qualified behavior professional. The first reason dogs may be fearful of storms is due to sound sensitivity.

SOUND SENSITIVE DOGS
Desensitization to thunder sounds: This involves purchasing a recording of thunderstorms and playing it at slowly increasing volume levels as dictated by a dog’s ability to relax at any given level of exposure.  Before you begin this technique, you want to observe your dog during the next storm – what are the first signs of fear?  Whining?  Pacing?  Spinning in circles?  Panting?  Write these symptoms down.

 

Then purchase your sound effects.   When there is not a active thunderstorm, turn the music  on and slowly raise the volume until your dog shows the first signs of nervousness.  Write down the volume level where these signs were first noted – when you begin your desensitization program, you will start at no less than two volume levels lower than that which produced the anxious response.

When you begin your program, you must play your sound effect at a level which does not elicit your dog’s fearful response.  The thunderstorm recording I use  is a rain storm with sporadic thunder.

There are many different variations and you may have to spend some time researching which recording replicates the thunderstorm sound that is most common to your area. Each time a clap of thunder is heard, offer your dog a high value reward, one that she loves and only receives when practicing this exercise.  Goal:  a) if your treat is truly high value, and b) if your dog is hungry, she should eat.

If both of these conditions apply and your dog will not eat, turn the thunderstorm sound effect down further.  When your dog begins to look at you expectantly, awaiting a tasty morsel each time she hears thunder, you may turn the volume up sightly.  If at any point you notice those early signs of anxiety, turn the volume down until she regains confidence. Continue until you can play the sound effect at a high volume.

Hperallergenic Dogs Part 1

Hypoallergenic Dogs

Most allergy specialists will recommend that individuals with pet allergies do not bring furry, dander-producing pets into their home. This is well-intended and sound advice – are dogs “good” for allergy sufferers? Physically, no. Allergy sufferers would likely be more physically comfortable not sharing their home with a furry pet. For allergy sufferers with mild to moderate reactions, the emotional benefits of having a pet trump the physical discomfort or a runny nose, sneezing, or itchy eyes.

If you’re one who will not be dissuaded, there are breeds which tend to produce relatively low-allergen dogs because they have hair and not fur. Generally, these breeds are characterized by an assortment of coat types:  very curly coated dogs ( Poodles, Portuguese Water Dogs, Bedlington Terriers, Bichon Frises), hairless dogs (Inca Orchid, Xolo, Chinese Crested Hairless, Hairless Rat Terrier), corded dogs ( Puli, Komondor), and wire-haired dogs (Wirehaired Fox Terrier, Broken Coat Parson/Jack Russell Terrier, Wirehaired Dachshund, Rough Coat Brussels Griffon, etc.). These breeds tend to have less fur than other breeds, but more importantly, generally shed less dander.

The curly-coated and corded dogs require significant grooming commitments. Many of these breeds are high energy and can be challenging – they require a lot of physical and mental stimulation to live happily in a home. Many of them require experienced dog owners and are not good “getting your dog ownership feet wet” breeds.

If you choose to bring a pet into the home despite the inevitable allergy symptoms, consult with your allergist about appropriate air filters and vacuums – clean frequently and thoroughly. Keep your dog out of the bedroom at all times. Bathe your dog once every four weeks using anti-allergenic shampoos. Ask your allergist about cleaning products that can help reduce the allergens in the home.

Many allergists will recommend that the dog should live outside. Virtually every behavior expert would strongly disagree. Dogs are social creatures and desire companionship. Your dog would much rather live in your house than in your yard, and relegating him to the backyard may produce any number of unwanted behaviors, including but not limited to: barking, digging, destruction of property; and are also subject to injury, poisoning, attacks by other dogs or wild animals and even unscrupulous humans. If you get a dog, make him part of your family by allowing him to live inside.

Doodles And Poos

Often, the designer dog craze, which revolves around mixing a poodle with nearly every other breed on the planet to play on the heartstrings and wallets of allergy sufferers seeking hypoallergenic dogs, is very  misleading to potential pet owners. Do not assume that mixed breeds with one poodle parent will automatically be low-allergen dogs.

Breeders of mixed breed dogs should be held to the same high standards as any breeders – insist on health checks appropriate to both parent breeds, meet both parents if possible (and the mother at a minimum), view the areas where the puppies will be whelped, ask for detailed descriptions of the type of socialization the puppies are provided with, look for breed-appropriate titles and conformation championships.

The Future Of Hypoallergenic Pets

Science has also taken notice of the pet-owning/allergy-suffering quandary. A company called Allerca has created what they call “lifestyle pets.” Allerca has allegedly produced the world’s first “scientifically proven hypoallergenic cats and dogs.” For as “little” as $5,000 (this is a special, limited time price) and as much as $16,000, you can bring one of these lifestyle pets into your home.

Obtaining one of these pets involves a 9-12 month wait list at this time. While these prices are out of reach for many pet allergy sufferers, the fact that this type of research is being done bodes well for the future of allergy sufferers who are also animal lovers. Perhaps someday, truly hypoallergenic pets will be available to individuals with dog and cat allergies.

Until then, there are a number of low-allergen dog breeds that are worth considering. Careful research will help you decide which breed is the best match for your family. Once you bring your new pet home, meticulous cleaning to remove dander from the environment, as well as allergy medication prescribed by your allergist, and keeping your dog’s coat clean and healthy will help keep the sneezing, wheezing, and red, itchy eyes to a minimum.

Thunderstorm Phobia Part 1

I feel that there may be (at least) three different causes for thunderstorm phobias.  Here are training techniques selected to address these problems may vary according to which aspects are triggering the phobic thundestorm response. These three are:

  • Fear of the sound of thunder: Does your dog’s fear response begin when he first hears the thunder?  Does he startle quickly at other loud, sharp sounds or sounds without easily identifiable sources?  Fireworks?  Cars backfiring?  A dropped pan?  Doors slamming?
  • Static electric change in the environment: Does your dog try to “ground himself” by seeking shelter in a bathtub, under a table on a ceramic floor tile, or on any sort of rubber matting?  Does your dog normally like touch but avoid your touch during a storm?
  • Change in barometric pressure: These are the dogs that generally try to get to “low ground” – running to hide in the basement, getting in a bathtub and not wanting to come up until the storm has passed.

These three factors are not mutually-exclusive, some dogs may trigger off all three triggers that are  mentioned, for them a combination of rehabilitation treatment techniques will be indicated.  For all three situations, the use of general calming aids may help you establish a less stressful environment for your dog.  Calmative aids may include:

  • Massage can reduce the chemicals associated with fear.
  • The Tapper combined with Dog Stress Reduction Program can have immediate results
  • Dog Appeasing Pheremone or DAP this is a synthetic replicate of a pheromone a dam would release while whelping her puppies to calm them.  It’s available in spray, collar, and plug-in form.
  • Aromatherapymy personal favorite is pharmaceutical grade lavender and vanilla essential oils diluted in distilled water.  BEWARE!  EO (essential oils) are not recommended for use in homes with resident kitties – their livers cannot appropriately metabolize EO in the environment, given internally, or applied to their skin.
  • Supplements.  She should be able to instruct you which, if any, may be appropriate for your dog and in what doses.  Some supplements which may help:  melatonin, valerian root, supplements containing kava, chamomile, passion flower, or lemon balm, B-vitamins, vitamin C, vitamin E, GABA, l-theanine, and 5-HTP.
  • Flower essences while many are familiar with Rescue Remedy (which is a blend of a variety of flower essences and availability in a variety of forms including sprays, topical creams, drops, etc.), few know that there is a very wild world of flower essences – the difference can be remarkable in dogs for whom the right essence or blend is found/created.
  • Dietary modification you may find that making changes to your dog’s diet can help reduce his anxiety.  Turkey-based foods are wonderful for anxious dogs who can tolerate them, l-tryptophan is an essential amino acid in turkey and is responsible for your feelings of sleepiness after Thanksgiving dinner! Adjusting levels of protein and carbohydrates according to your dog’s needs and incorporating whole, fresh foods may make dramatic changes in his behavior.
  • Standard Western Medicationsprescription medications for anxiety reduction are available and their use may be indicated in some dogs.  When indicated, their use may be permanent or temporary depending on the dog.  Meds alone will not solve this problem, so while you can talk to your vet about medication and if it may be right for your dog, expect to do dog behavior training to reduce his anxiety as well.

Spring: Easter, Mother’s Day and Snake Season

Snakes. But snakes can be a real consideration when enjoying life in the great outdoors with man’s best friend. Snakes are found not only in the wilds of nature, but in our backyards.

Dog snake bites are more common in the southern and western states, but can happen anywhere. Snake bites will most often occur between March and October when snakes are the most active and searching for mates.

Every snake bite must be treated as an emergency situation. A venomous snake bite can be fatal and a bite from a non-venomous snake can be very harmful to your dog.

When taking your dog for a walk be sure to use a leash or have an off-leash recall and keep a large distance from abandoned buildings, brush, bushes, long grass, and rocky areas that make great hiding places for snakes. Our Chicago dog boot camp will train your dog to come when called off-leash, a life saving command.

Rosie The Rough and Tumble Lab-Updates

Hello-
I have a great progress report for Rosie, the dominant chocolate labrador.  :)

I am still have a little trouble with getting a prong collar and leash on Rosie though I have found a way of backing her into a corner so she can’t move and then she calms down so I can put the collar and leash on.  This is probably not the long term solution so we need more work on this.    I have not had anyone over yet so we have not worked on her behavior when people come over.

I am doing better too.  I am more calm and less stressed.  We are adapting to new routines and behaviors.

  • She is sleeping in her crate at night and only wakes up once or twice during the night with a small whine.
  • I can say quiet once from another room and she is quiet.
  • She has not barked in the crate since Ami left last Monday.
  • And she sits now in the crate and waits until I open the door.  Sometimes she forgets but I remind her by closing the crate door so she must sit every time before she can leave the crate.
  • She also is not jumping on the furniture much now and she knows she is not supposed to be on the couch especially when I am on the couch.  I have both my dogs laying on the floor in front of me now when I watch TV and this makes me calmer and relaxed and the dogs are not unhappy either.
  • We also worked on dogs waiting to go through door until I invite them or I go through first.  Rosie is very good with this action as well.  I continue to reinforce all these things daily though since we are not perfect yet.
  • Rosie finally will take the tennis ball in her mouth with the command take and lets it go with give.  She learned it but she didn’t want to do it right away.  But she did it for me several times yesterday.

Thank you,
CS

Ear Infections: The Most Common Dog Health Problem

The most common dog ailments that can influence behavior are ear infections. Ear infections in dogs are very uncomfortable and luckily are typically easy to detect by human caretakers. Watch for your dog to be repeatedly shaking his or her head or for excessive itching of his or her ears. Look inside the ears for inflammation, redness or smelly discharge. Tilting of the head to one side is another common sign of an infection. If you suspect an ear infection, then an immediate veterinary examination is necessary. Untreated ear infections are not just extremely painful for your dog but they can lead to greater problems including closure of the ear canal. Typical causes of canine ear infections include mites, bacteria, excessive wax, matted hair, or abnormal drainage.

Dog Whispering in Theory and Practice

For species that live in packs it’s important to be able to communicate with its own kind. Both in order to cooperate when they hunt, to bring up their offspring, and perhaps most importantly: to live in peace with each other. Conflicts are dangerous – they cause physical injuries and a weakened pack, which is something that no pack can afford – it will cause them to go extinct.

Dogs live in a world of sensory input: visual, olfactory, auditory perceptions. They easily perceive tiny details – a quick signal, a slight change in another’s behavior, the expression in our eyes. Pack animals are so perceptive to signals that a horse can be trained to follow the contraction in our pupils and a dog can be trained to answer your whispering voice. There’s no need to shout commands, to make the tone of our voice deep and angry – what Karen Pryor refers to as swatting flies with a shovel.

The dogs have about 30 calming signals, perhaps even more. Most dogs use some of these signals, while other dogs have an incredibly rich ´vocabulary´. It varies from dog to dog.

The problem

Dogs use this communication system towards us humans, simply because it’s the language they know and think everyone understands.

By failing to see your dog using calming signals on you, and perhaps even punish the dog for using them, you risk causing serious harm to your dog. Some may simply give up using the calming signals, including with other dogs. Others may get so desperate and frustrated that they get aggressive, nervous or stressed out as a result. Puppies and young dogs may actually go into a state of shock.

Basic knowledge

Dad calls Spot and has learned in class that he needs to sound strict and dominant so that Prince will understand who is in charge. Spot finds dad’s voice to be aggressive, and being a dog he instantly give dad a calming signal in order to make him stop being aggressive. Spot will perhaps lick his own nose, yawn, turn away – which will result in dad becoming angry for real, because dad perceives Prince as being pig-headed, stubborn and disobedient. Spot is punished for using his calming signals to calm dad. This is a typical example of something that happens on an everyday basis with many dog owners.

We need to learn to understand the language of dogs so that we can understand what our dogs are telling us. That is the secret of having a good life together.

How the dog is using the calming signals

Yawning

The dog may yawn when someone bends over him, when you sound angry, when there’s yelling and quarreling in the family, when the dog is at the vet’s office, when someone is walking directly at the dog, when the dog is excited with happiness and anticipation – for instance by the door when you are about to go for a walk, when you ask the dog to do something he doesn’t feel like doing, when your training sessions are too long and the dog gets tired, when you have said NO for doing something you disapprove of, and in many other situations.

Threatening signals (to walk straight at, reach for the dog, bending over the dog, staring into the dog’s eyes, fast movements, and so on) will always cause the dog to use a calming signal. There are about 30 different calming signals, so even when many dogs will yawn, other dogs may use another calming signal.  All dogs know all the signals. When one dog yawns and turn his head to the side, the dog he is ´talking to´ may lick his nose and turn his back – or do something completely different.  The signals are international and universal. All dogs all over the worlds have the same language. An elkhound that lives in an isolated valley in Norway would understand a dog from Japan. They will have no communication problems!

Licking

Licking is another signal that is used often. Especially by black dogs, dogs with a lot of hair around their faces, and others who’s facial expressions for some reasons are more difficult to see than those of dogs with lighter colors, visible eyes and long noses. But anyone can use licking, and all dogs understand it no matter how quick it is. The quick little lick on the nose is easier to see if you watch the dog from in front. It’s best seen if you can find somewhere you can sit in peace and quiet and observe. Once you have learned to see the lick, you will also be able to see it while walking the dog.

Sometimes it’s nothing more than a very quick lick, the tip of the tongue is barely visible outside the mouth, and only for a short second. But other dogs see it, understand it and respond to it. Any signal is always returned with a signal.

Turning away/turning of the head

The dog can turn its head slightly to one side, turn the head completely over to the side, or turn completely around so that the back and tail is facing whoever the dog is calming. This is one of the signals you may see most of the time in dogs.

When someone is approaching your dog from in front, he will turn away in one of these ways. When you seem angry, aggressive or threatening, you will also see one of these variations of the signal. When you bend over a dog to stroke him, he will turn his head away from you. When you make your training sessions too long or too difficult, he will turn his head away from you. When the dog is taken by surprise or take someone by surprise, he will turn away quickly. The same happens when someone is staring or acting in a threatening way.

In most cases, this signal will make the other dog calm down. It’s a fantastic way in which to solve conflicts, and it’s used a lot by all dogs, whether they are puppies or adults, high or low ranking, and so on. Allow your dog to use it! Dogs are experts at solving and avoiding conflicts – they know how to deal with conflicts.

Play bow

Going down with front legs in a bowing position can be an invitation to play if the dog is moving legs from side to side in a playful manner. Just as often, the dog is standing still while bowing and is using the signal to calm someone down. These signals often have double meanings and may be used in many different ways – often the invitation to play is a calming signal by itself because the dog is making a potentially dangerous situation less tense and diverts with something safe.

Recently, in a puppy class with a mix of puppies, one of them was afraid of the others in the beginning. The others left him alone and respected his fear. In the end he would dare to approach the others. When he did, he went into a play bow as soon as one of the other dogs looked at him. It was an obvious combination of slight fear of the others, as well as wanting to take part in the playing.

When two dogs approach each other too abruptly, you will often see that they go into a play bow. This is one of the signals that are easy to see, especially because they remain standing in the bow position for a few seconds so that you have plenty of time to observe it.

Sniffing the ground

Sniffing the ground is a frequently used signal. In groups of puppies you will see it a lot, and also when you and your dog is out walking and someone is coming towards you, in places where there’s a lot going on, in noisy places or when seeing objects that the dog isn’t sure of what is and find intimidating.

Sniffing the ground may be anything from moving the nose swiftly down toward the ground and back up again – to sticking the nose to the ground and sniff persistently for several minutes. Is someone approaching you on the pavement? Take a look at your dog. Did he drop the nose down toward the ground, even slightly? Did he turn his side to the one approaching and sniff the side of the road?  Of course, dogs sniff a lot, also in order to ´read the paper´ and enjoy themselves. Dogs are pre-programmed to use their noses and it’s their favorite activity. However, sometimes it’s calming – it depends on the situation. So pay attention to when and in which situations the sniffing occur!

Walking slowly

High speed will be seen as threatening to many dogs, and they might want to go in to try and stop the one who is running. This is partly a hunting behavior and is triggered by the sight of a running human or dog. If the one running is coming straight at the dog, it involves a threat and a defense mechanism sets in.

A dog that is insecure will move slowly. If you wish to make a dog feel safer, then you can move slower. When I see a dog react to me with a calming signal, I immediately respond by moving slower.

Is your dog coming very slowly when you call him? If so, check the tone of your voice – do you sound angry or strict? That may be enough for him to want to calm you down by walking slowly. Have you ever been angry with him when he came to you? Then this may be why he doesn’t trust you. Another reason to calm you may be if the dog is always put on a leash when coming when called. Take a look at your dog the next time you call him. Does he give you any calming signals when coming? If he moves slowly, you may need to do something different in the way you act.

Freezing

“Freezing” – is what we call it when the dog is stopping while standing completely still, sitting or laying down and remain in that position. This behavior is believed to have something to do with hunting behavior – when the prey is running, the dog attacks. Once the prey stops, the dog will stop too. We can often see this when dogs are chasing cats. This behavior, however, is used in several different situations. When you get angry and aggressive and appear threatening, the dog will often freeze and not move in order to make you be good again. Other times the dog may walk slowly, freeze, and then move slowly again. Many owners believe that they have very obedient dogs that is sitting, lying down or standing completely still. Perhaps they are actually using calming signals? Very often a dog will stop and remain calm when someone is approaching. If your dog wants to stop or move slowly in a situation like that, then let him. Also, should your dog be in a conflict situation with a human or dog, and is unable to escape, freezing may be one way to calm the other dog or person.

Sitting down/lifting one paw

I have only rarely seen dogs lift their paw as a calming signal, but on a few occasions it’s clearly been used to calm another dog.

To sit down, or an even stronger signal, to sit down with the back turned towards someone – for instance the owner – has a very calming effect. It’s often seen when one dog wants to calm another dog that is approaching too quickly. Dogs may sit down with their backs turned against the owner when he or she sounds too strict or angry.

Walking in curve

This signal is frequently used as a calming signal, and it is the main reason why dogs may react so strongly towards meeting dogs when they are forced to walk straight at someone. Their instincts tell them that it is wrong to approach someone like that – the owner says differently. The dog gets anxious and defensive. And we get a dog that is barking and lunging at other dogs, and eventually we have an aggressive dog.

Dogs, when given a chance, will walk in curves around each other. That’s what they do when they meet off leash and are free to do things their own way. Allow your dog to do the same when he’s with you.

Some dogs needs large curves, while others only need to walk slightly curved. Allow the dog decide what feels right and safe for him, then, in time and if you want to, he can learn to pass other dogs closer.

Let the dog walk in a curve around a meeting dog! Don’t make him walk in a heel position while you’re going straightforward – give him a chance to walk in a curve past the meeting dog. If you keep the leash loose and let the dog decide, you will often see that the dog chooses to walk away instead of getting hysterical.

For the same the reason, don’t walk directly toward a dog, but walk up to it in a curve. The more anxious or aggressive the dog is, the wider you make the curve.

Other calming signals

By now you have learned about some of the more common calming signals. There are around 30 of them, and many have yet to be described. I will mention a few more briefly so that you can make further observations:

  • “Smiling”, either by pulling the corners of the mouth up and back, or by showing the teeth as in a grin.
  • Smacking the lips
  • Wagging the tail – should a dog show signs of anxiety, calming or anything that clearly has little to do with happiness, the wagging of the tail isn’t an expression of happiness, but rather that the dog wants to calm you.
  • Urinating on himself – A dog who is cowering and crawling toward his owner while wetting himself and waving his tail, is showing three clear signs of calming – and of fear. Wanting to get up into your face and lick the corners of your mouth.
  • Making the face round and smooth with the ears close to the head in order to act like a puppy. (No one will harm a puppy, is what the dog believes)
  • Lying down with the belly against the ground. This has nothing to do with submission – submission is when the dog lays down with the belly up. Lying down with the belly towards the ground is a calming signal.
  • And there are even more calming signals that are used in combination with others. For instance, a dog may urinate at the same time as he is turning his back to something. This is a clear sign of calming by for instance an annoying adolescent dog.

Some dogs act like puppies, jumping around and act silly, throwing sticks around, etc. if they discover a fearful dog nearby. It’s supposed to have, and does have, a calming effect.

Meeting situations

A meeting situation between two strange dogs will almost never show signs of strong submission or what people refer to as dominant behavior. A meeting situation between two dogs will usually be something like this:

King and Prince see each other at 100 feet range and are headed toward each other. They start sending each other message the moment they see each other. Prince stops and stands still (´freezes´), and King is walking slowly while he keeps glancing at the other dog through the corner of his eye.

As King gets closer, Prince starts licking his nose intensely, and he turns his side to King and starts sniffing the ground too. Now King is so close that he needs to be even more calming, so he starts walking in a curve and away from Prince – still slowly and now he is licking his nose too. Prince sits down, and looks away by turning his head far to one side.

By now the two dogs have ´read´ each other so well that they know whether they wish to go over and greet each other, or if this could get so intense that it is best to stay away from each other.

Never force dogs into meeting others

Allow the dogs to use their language in meeting situations so that they feel safe. Sometimes they will walk up to each other and get along, other times they feel that it’s safer to stay at a distance – after all, they have already read each other’s signals, they do so even at a several hundred meters distance – there’s no need to meet face to face.

In Canada, dog trainers who attended my lecture, came up with a new name of these calming signals: ´The Language of Peace”. That’s exactly what it is. It’s a language, which is there to make sure that dogs have a way to avoid and solve conflicts and live together in a peaceful manner. And the dogs are experts at it.

Start observing and you will see for yourself. Most likely, you will get a much better relationship with your dog and other dogs; too, once you are beginning to realize what the dog is really telling you. It’s likely that you will understand things you earlier were unable to figure out. It is incredibly exciting, as well as educational.

The Three Brains of Your Dog: Head, Heart and Gut

Did you know that your body has three brains? Your body has “brains” in your head, your heart and your gut. All three brains can influence your behavior and the behavior of your dog. Here is a great article that addresses this issue in regards to depression in people.

 

Most people fail to realize that your gut is quite literally your second brain, and actually has the ability to significantly influence your:

  • Mind
  • Mood
  • Behavior

So while modern psychiatry still falsely claims that psychological problems such as depression are caused by a chemical imbalance in your brain, researchers keep finding that depression and a variety of behavioral problems actually appear to be linked to an imbalance of bacteria in your gut!

Germ-Free Mice Engage in High-Risk Behavior

In the featured study published last month in Neurogastroenterology & Motility, mice that lack gut bacteria were found to behave differently from normal mice, engaging in what would be referred to as “high-risk behavior.” This altered behavior was accompanied by neurochemical changes in the mouse brain.

According to the authors, microbiota (your gut flora) may play a role in the communication between your gut and your brain, and:

“Acquisition of intestinal microbiota in the immediate postnatal period has a defining impact on the development and function of the gastrointestinal, immune, neuroendocrine and metabolic systems. For example, the presence of gut microbiota regulates the set point for hypothalamic-pituitary-adrenal (HPA) axis activity.”

The neurotransmitter serotonin activates your hypothalamic-pituitary-adrenal axis by stimulating certain serotonin receptors in your brain. Additionally, neurotransmitters like serotonin can also be found in your gut. In fact, the greatest concentration of serotonin, which is involved in mood control, depression and aggression, is found in your intestines, not your brain!

So it actually makes perfect sense to nourish your gut flora for optimal serotonin function as it can have a profound impact on your mood, psychological health, and behavior.

The authors concluded that:

“[T]he presence or absence of conventional intestinal microbiota influences the development of behavior…”

This conclusion adds support to another recent animal study, which also found that gut bacteria may influence mammalian early brain development and behavior. But that’s not all. They also discovered that the absence or presence of gut microorganisms during infancy permanently alters gene expression.

Through gene profiling, they were able to discern that absence of gut bacteria altered genes and signaling pathways involved in learning, memory, and motor control. This suggests that gut bacteria is closely tied to early brain development and subsequent behavior. These behavioral changes could be reversed as long as the mice were exposed to normal microorganisms early in life. But once the germ-free mice had reached adulthood, colonizing them with bacteria did not influence their behavior.

According to Dr. Rochellys Diaz Heijtz, lead author of the study:

“The data suggests that there is a critical period early in life when gut microorganisms affect the brain and change the behavior in later life.”

In a similar way, probiotics have also been found to influence the activity of hundreds of your genes, helping them to express in a positive, disease-fighting manner.

The Gut-Brain Connection

When you consider the fact that the gut-brain connection is recognized as a basic tenet of physiology and medicine, and that there’s no shortage of evidence of gastrointestinal involvement in a variety of neurological diseases, it’s easy to see how the balance of gut bacteria can play a significant role in your psychology and behavior as well.

With this in mind, it should also be crystal clear that nourishing your gut flora is extremely important, from cradle to grave, because in a very real sense you have two brains, one inside your skull and one in your gut, and each needs its own vital nourishment.

Interestingly, these two organs are actually created out of the same type of tissue. During fetal development, one part turns into your central nervous system while the other develops into your enteric nervous system. These two systems are connected via the vagus nerve, the tenth cranial nerve that runs from your brain stem down to your abdomen. This is what connects your two brains together, and explains such phenomena as getting butterflies in your stomach when you’re nervous, for example. (For an interesting and well-written layman’s explanation of this connection, read through Sandra Blakeslee’s 1996 New York Times article Complex and Hidden Brain in Gut Makes Stomachaches and Butterflies.)

Your gut and brain work in tandem, each influencing the other. This is why your intestinal health can have such a profound influence on your mental health, and vice versa.

As a result, it should be obvious that your diet is closely linked to your mental health. Furthermore, it’s requires almost no stretch of the imagination to see how lack of nutrition can have an adverse effect on your mood and subsequently your behavior.

Have We Become Too Sanitized for Our Own Sanity?

Another study published last year in the Archives of General Psychiatry reviewed the evidence for signs that psychiatric problems might be caused by lack of natural microorganisms in soil, food, and the gut. And it did find such a link.

Rates of depression in younger people have steadily grown to outnumber rates of depression in the older populations, and one reason for this could be the lack of exposure to bacteria, both outside and inside your body.

Quite simply, modern society may have gotten too sanitized and pasteurized for our own good.

Fermented foods have been traditional staples in most cultures, but modern food manufacturing, with its focus on killing ALL bacteria in the name of food safety, has eliminated most of these foods. You can still find traditionally fermented foods like natto or kefir, but they’re not the dietary staples they once used to be, and many people don’t like them when trying them out for the first time in adulthood.

When you deprive your child of all this bacteria, her immune system—which is her primary defense system against inflammation—actually gets weaker, not stronger. And higher levels of inflammation are not only a hallmark of heart disease and diabetes, but also of depression.

The authors explain it as follows:

Significant data suggest that a variety of microorganisms (frequently referred to as the “old friends”) were tasked by coevolutionary processes with training the human immune system to tolerate a wide array of non-threatening but potentially proinflammatory stimuli. Lacking such immune training, vulnerable individuals in the modern world are at significantly increased risk of mounting inappropriate inflammatory attacks on harmless environmental antigens (leading to asthma), benign food contents and commensals in the gut (leading to inflammatory bowel disease), or self-antigens (leading to any of a host of autoimmune diseases).

Loss of exposure to the old friends may promote major depression by increasing background levels of depressogenic cytokines and may predispose vulnerable individuals in industrialized societies to mount inappropriately aggressive inflammatory responses to psychosocial stressors, again leading to increased rates of depression.

… Measured exposure to the old friends or their antigens may offer promise for the prevention and treatment of major depression in modern industrialized societies.”

Researchers around the World have Linked Gut Problems to Brain Disorders

Brain disorders can take many forms, one of which is autism. In this particular area you can again find compelling evidence of the link between brain and gut health. For example, gluten intolerance is frequently a feature of autism, and many autistic children will improve when following a strict gluten-free diet. Many autistic children also tend to improve when given probiotics, either in the form of fermented foods or probiotic supplements.

Dr. Andrew Wakefield is just one of many who have investigated the connection between developmental disorders and bowel disease. He has published about 130-140 peer-reviewed papers looking at the mechanism and cause of inflammatory bowel disease, and has extensively investigated the brain-bowel connection in the context of children with developmental disorders such as autism.

A large number of replication studies have also been performed around the world, by other researchers, confirming the curious link between brain disorders such as autism and gastrointestinal dysfunction. For a list of more than 25 of those studies, please see this previous article.

Other Health Benefits of Probiotics

Your body contains about 100 trillion bacteria — more than 10 TIMES the number of cells you have in your entire body. Ideally, the ratio between the bacteria in your gut is 85 percent “good” and 15 percent “bad.”

In addition to the psychological implications discussed above, a healthy ratio of good to bad gut bacteria is essential for:

  • Protection against over-growth of other microorganisms that could cause disease
  • Digestion of food and absorption of nutrients
  • Digesting and absorbing certain carbohydrates
  • Producing vitamins, absorbing minerals and eliminating toxins
  • Preventing allergies

Signs of having an excess of unhealthy bacteria in your gut include gas and bloating, fatigue, sugar cravings, nausea, headaches, constipation or diarrhea.

What Interferes With Healthy Gut Bacteria?

Your gut bacteria do not live in a bubble; rather, they are an active and integrated part of your body, and as such are vulnerable to your lifestyle. If you eat a lot of processed foods, for instance, your gut bacteria are going to be compromised because processed foods in general will destroy healthy microflora and feed bad bacteria and yeast.

Your gut bacteria are also very sensitive to:

  • Antibiotics
  • Chlorinated water
  • Antibacterial soap
  • Agricultural chemicals
  • Pollution

Because of these latter items, to which virtually all of us are exposed at least occasionally, it’s generally a good idea to “reseed” the good bacteria in your gut by taking a high-quality probiotic supplement or eating fermented foods.

Tips for Optimizing Your Gut Bacteria

Getting back to the issue of inflammation for a moment, it’s important to realize that an estimated 80 percent of your immune system is actually located in your gut, which is why you need to regularly reseed your gut with good bacteria.

Additionally, when you consider that your gut is your second brain AND the seat of your immune system, it becomes easy to see how your gut health can impact your brain function, psyche, and behavior, as they are interconnected and interdependent in a number of different ways—several of which are discussed above.

In light of this, here are my recommendations for optimizing your gut bacteria.

  • Fermented foods are still the best route to optimal digestive health, as long as you eat the traditionally made, unpasteurized versions. Healthy choices include lassi (an Indian yoghurt drink, traditionally enjoyed before dinner), fermented milk such as kefir, various pickled fermentations of cabbage, turnips, eggplant, cucumbers, onions, squash and carrots, and natto (fermented soy).If you regularly eat fermented foods such as these that, again, have not been pasteurized (pasteurization kills the naturally occurring probiotics), your healthy gut bacteria will thrive.
  • Probiotic supplement. Although I’m not a major proponent of taking many supplements (as I believe the majority of your nutrients need to come from food), probiotics are definitely an exception. I have used many different brands over the past 15 years and there are many good ones out there. I also spent a long time researching and developing my own, called Complete Probiotics, in which I incorporated everything I have learned about this important tool over the years.If you do not eat fermented foods, taking a high quality probiotic supplement is definitely recommended.
