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.
Today there are over 400 recognized breeds of dogs in the world. Many of them have historical origins dating back hundreds, even thousands of years. Wherever humans have lived, dogs have been alongside them performing various tasks. One of the reasons dogs have been such a successful species is because they are so adaptable. They have made themselves useful in countless ways to humans so we kept feeding them, providing shelter for them, and, yes, breeding them. It’s no accident that we have dogs able to hunt, herd, guard, track, and do so many other things at an expert level. Humans figured out early on that if you bred dogs that were good at these things, you would get offspring that were also good at doing them. All of these jobs performed by dogs were necessary for our own species to survive. It’s no secret that we owe a lot to dogs, just as we do to other animals.
For example, a bill currently under consideration in New Jersey would ban breeders from selling dogs outside the state unless the sale was made face-to-face. If you are a breeder in New Jersey and a potential buyer in say, California, is interested in one of your dogs, this buyer would have to come to New Jersey to see and buy the dog. Or the breeder would have to take the dog to California. This is obviously onerous and unnecessary. It also adds a tremendous expense to the cost of the dog. This kind of legislation is proposed in the name of “consumer protection” but it is actually meant to punish and discourage dog breeding.
If you own one of the 11 "riskiest" dog breeds -- which include Rottweilers, Pit Bulls and Doberman Pinschers -- you may face some big homeowners or renters insurance headaches, even if the only things your pup has ever taken a bite of are his Alpo and bone. These days, companies offering homeowners and renters insurance are pickier than ever about which types of dogs they’ll insure and which they won’t
