Human beings have been partners with dogs for a very long time—at least 25,000 years. More recent discoveries suggest that the partnership may be as much as 100,000 years old. And during all of that time humans have been intervening in the breeding of dogs—that’s what turned wolves into dogs in the first place.
For the last 40 years there’s been an ongoing experiment in Siberia in domestication that casts some highly suggestive light on just how wolves became dogs. Scientists there have been selectively breeding foxes for a single characteristic: tamability or friendliness to humans. And over the course of the experiment the foxes in the program have begun to express some of the other kinds of characteristics that differentiate dogs from wolves besides friendliness to humans: appearance of dwarf and giant varieties, piebald coat color, curly tails, floppy ears, etc.
Early human beings certainly must have noticed some of these characteristics and selectively bred their dogs companions to be better and more useful companions.
Today there are more than 150 breeds of dogs with physical and mental characteristics that pre-dispose them to excel at certain tasks. There are hunting dogs that excel at finding, trailing, flushing, or retrieving game. There are herding dogs that excel at herding or droving livestock. There are terriers bred to hunt vermin. There are working dogs that excel at pulling, or swimming, or guarding. And, of course, there are breeds of dogs that excel at being good and loving companions to people. These breeds have been shaped over thousands and thousands of dog generations.
Occasionally you’ll hear the complaint from some well-meaning souls that dogs are being forced to work. Not only is this not true but, as someone who has actually worked dogs (sledding, carting, packing, herding, and care-taking), I can tell you the actual case couldn’t be more opposite. You can’t force a dog to pull a sled or to herd. Either they’ll do it or they won’t. If the dog decides he doesn’t want to pull that sled, he’ll sit down and there’s nothing you can do to make him pull.
And, in fact, something miraculous happens when a dog is doing the work that he or she was bred for. Their entire demeanor changes and they express a kind of keenness and transcendent joy that’s wonderful to see. So this is what I have the thick coat, and the feet shaped to run through snow, the strong legs, and shoulders and chest that yearn to pull for. Let’s go!
We poor random-bred humans can barely appreciate that kind of joy, knowing why we were born and throwing ourselves into it with our whole hearts and our whole souls. With us only the greatest of saints have that experience. It’s every purebred dog’s birthright.
My wife and Jenny, our Lady-O, just took off a little while ago to go to the hospital to visit sick people there as part of Jenny’s therapy dog activities. That’s part of the work that our beloved Samoyed breed was bred for—to love and take care of people who need them. You should have seen the joy in her eyes as she walked out the door! She knew where she was going.
