Breed identification and purebred/mixed breed dogs
Breed-specific legislation, by definition, restricts dogs based on their breed. This requires breed identification of each and every dog.
Breed identification might be easy when a dog is purebred, has a pedigree, and is registered with a kennel club. However, this makes up only a very small fraction of all dogs in the U.S. In 2006, an estimated 72 million dogs lived in households in the U.S. (U.S. Pet Ownership & Demographics Sourcebook (2007 Edition)) How many of these dogs are purebred, pedigreed, and registered? Though I have seen one estimate put the number at 25 percent, I believe that to be extremely high. The actual number of purebred, pedigreed, registered dogs is difficult, if not impossible, to estimate.
Even using this highest estimate, that leaves 75 percent or more of the U.S. canine population without any sort of traceable lineage. Some of these dogs are undoubtably purebred, though they may lack any sort of historical paper trail to prove it. Their appearance is close enough to a breed standard that owners can confidently say that their dog is of a specific breed.
The vast majority of canines, however, are mixed breed dogs. And though we tend to think of mixed breed dogs as the offspring of two purebred dogs (Mastiff x Boxer = Mastiff-Boxer mix), the reality is far more complex. Most mixed breed dogs are a genetic mishmash resulting from several generations of mixed breed dogs interbreeding. The end result is incredibly complex.
To make things more confusing, a dog that doesn’t really meet any single breed standard may be categorized as a type of dog rather than a specific breed. Dogs may be identified as terriers, pit bulls, shepherds, or retrievers; none of these are actual breed names, and the breeds that really do make up these categories come in a startling variety of shapes, sizes, and colors. There’s a huge difference between an Airedale Terrier and a Jack Russell Terrier, so what does a “terrier mix” describe?
