A dog’s behavior depends on both genes and environment. According to recent studies, of the 20,000 genes in the canine genome, approximately only 50 determine physical appearance (height at the withers, shape of the head, carriage of the ears and tail, length of the tail, color and texture of the coat, and so on). Therefore, two dogs of the same breed have only 0.25% of common genetic heritage. This tiny percentage of the dog’s genetics does not make every dog of the same breed a carbon copy of the others. Between two lines of the same breed, there are sometimes more behavioral differences than between dogs of two different breeds altogether.

It is impossible to predict behavior based on physical appearance alone.

Dogs of the same breed are not clones, even though they may look very similar.
