Today some of these jobs are performed in other ways and dogs don’t do the work they used to do. Hunting is a sport today and most of us don’t have to hunt with dogs to put food on the table. English Cocker Spaniels and Irish Setters are more popular as family pets than as hunting dogs. Dogs aren’t commonly used to kill rats today and it’s been a long time since the adorable Yorkshire Terrier, originally bred to kill vermin in textile mills, was used for this kind of work. Dogs still have some specialized uses for search and rescue, narcotics detection and other kinds of detection, along with other specialized skills such as therapy dog work, but most people don’t need to use dogs for work. Nevertheless, breeds still have their admirers. Some people love a dog’s appearance. Some people love a breed because they are from the same tiny corner of the world and they feel a kinship with the dogs of their ancestors. Some people love the temperament of a certain breed or its athletic ability. There are all kinds of reasons why people love a particular breed.
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.
When large dogs eliminate, they eliminate a lot more than small dogs. More goes in and more comes out of large breeds. Which is something to keep in mind if your dog will live inside - especially if you live in a high rise apartment and he will have to be litter box trained (there is always going to be more to clean up).
What you may not know is that many breeds today have very small populations. If some breeds were any other kind of animal they would be considered endangered. You may find it hard to believe, but breeds can become extinct. If you read any histories about dog breeds, you will find lots of references to breeds that are gone now. Countless breeds have become extinct over the centuries. In some cases we have some of their descendants because they contributed to newer breeds, but not always. Some people might not care if particular breeds become extinct, but if you are a fan of a breed, then this might matter to you. From a genetic viewpoint, it’s always good to have a wide selection of dogs that contributed to a breed’s foundation. You never know when it might be necessary to reintroduce some of the genes from an older breed for health reasons. If those breeds are extinct, that’s no longer a possibility.
