The study found distinct genetic clusters within modern dogs that largely corresponded to phenotype or function. These included spitz-breeds, toy dogs, spaniels, Mastiff-like breeds, small terriers, retrievers, herding dogs, scent-hounds, and sight-hounds. There were 17 breeds that conflicted with phenotype or function and these were thought to be the result of crossing some of the other phenotypes. As in a 2004 study that found 9 ‘ancient breeds’ to be genetically divergent, the study found 13 breeds that were genetically divergent from the modern breeds: the Basenji, Saluki, Afghan hound, Samoyed, Canaan dog, New Guinea singing dog, dingo, Chow Chow, Chinese Shar Pei, Akita, Alaskan malamute, Siberian husky and American Eskimo dog. Results also indicated that the Basenji had recent admixture with Middle Eastern wolves.
Before you say that the person in California could find another dog closer to home, what if the New Jersey breeder is one of the few people in the country breeding that particular breed? In many cases we are talking about breeds that may only register a few litters per year. That’s why this kind of legislation is so dangerous. In some cases it could literally cause the extinction of breeds. Breeders give up breeding rather than face these kinds of legislative problems.
The following list uses a wide interpretation of "breed." Breeds are usually categorized by the functional type from which the breed was developed. The basic types are companion dogs, guard dogs, hunting dogs, herding dogs, and working dogs, although there are many other types and subtypes. Breeds listed here may be traditional breeds with long histories as registered breeds, rare breeds with their own registries, or new breeds that may still be under development.
Getting a dog is not just an emotional commitment; it is also a financial one, too. But when it comes to money, not all dogs are created equal. A bit of research goes a long way in discovering which dog breed is best for your budget.
