True purebred dogs have distinct genetic characteristics that are uniquely their own. Each dog breed has a set of clearly outlined standards for the dog’s behavior, physique and temperament. It is thus easier to recognize purebred puppies by their initial form and figure, and less so with mixed pups.
This is the first of many advantages to purchasing purebred dogs. If you are interested in a dog that will perform a specific job, the right breed of puppy can be chosen, trained, and put out on the field. On the other hand, you may want a dog with qualities that fit your own lifestyle, such as a dog with a small stature, one that enjoys playing with other animals, or one that does not shed very much.
One interesting fact is that most dog breeds are the creations of human beings over the last 300 years. Most dog shows only accept the registration of purebred dogs, with papers to prove their lineage. This is the main reason why pureblood puppies are usually more expensive and harder to find than mixed ones.
How Purebred Dogs Are Officially Recognized
The crucial event for any breed is to be recognized by a professional kennel club such as the AKC (American Kennel Club) or the CKC (Canadian Kennel Club). The Chihuahua, for example, was not recognized as a separate breed until the year 1904. After this, breeders and owners alike could register their dogs in shows and they were treated as any other domesticated dog breed.
