Things You'll Need
- Papers accompanying puppy
- Breed standard books
- Reputable breeder or knowledgeable veterinarian
- Dog DNA test kit
Instructions
Check through the papers that came with your puppy from the breeder. If you own a purebred puppy, it would have come with pedigree papers and registration papers from a reputable kennel club or pedigree service. An American pit bull terrier puppy, for instance, very likely will be registered with the United Kennel Club, whereas Staffordshire bull terrier or American Staffordshire terrier puppies would likely be registered with the American Kennel Club.
Look up the standards for the American pit bull terrier, the American Staffordshire terrier and the Staffordshire bull terrier in a good breed book and compare your puppy to them. You may not be able to see particular traits, however, until your pit bull puppy is older and better developed.
Have a professional dog breeder who specializes in breeding pit bulls see your puppy and give you an opinion. He should be able to tell if your pit bull may be full blooded. Some veterinarians also may be able to give you an appraisal.
Invest in a DNA kit test to see what breeds are detected in your puppy's blood lines. The Wisdom Panel test kit, for instance, can trace your pit bull's ancestry and detect the presence of American Staffordshire terrier and Staffordshire bull terrier components. These tests cannot determine100 percent breed purity, but at least can prove a dog is 75 percent from one specific breed.
