This a list of dog breeds divided into groups based upon their historical purposes, that are recognized in America today. Each breed will be sorted into our Green Light, Yellow Light, Red Light temperament categories as well as size.
We have devised our own unique grouping of dogs that is very different from the manner in which the big breed clubs group dog breeds. We have grouped dogs not just by historical purpose, size or country or origin, but instead by temperament and energy level. We have taken the liberty to create categories; Green Light, Red Light and Yellow Light that describe which breed will do best in a particular lifestyle situation.
We call this the Traffic Light Temperament Test ™ and it is based upon a universally recognized symbol, the Traffic Light. A traffic light has three colors green, yellow and red. These colors have the same meaning all over the world. Green means go, Red means stop and Yellow means slow down. We have found that it is easy to categorize dogs into these three divisions.
