If your heart is set on purchasing an American Pit Bull Terrier,
you'll need to be scrupulous in your search for a reputable breeder. Many cities are now outlawing the breed because of all the bad publicity they get, and unfortunately the fault is with the humans more than the dogs.
The American Kennel Club does not recognize the American Pit Bull breed, and the closest thing they will acknowledge is the American Staffordshire Terrier. Dogs like the famous Spuds McKenzie and one owned by General George Patton are Bull Terriers, and not to be confused with pit bulls. Of course, the name "Pit Bull" was coined from the bull terriers being fought to the death in pits, a horrible "sport" that is outlawed today. The dogs are banned in many places because illegal fighting is still carried on, and these dogs are also owned by drug dealers and felons who use them to stand guard over their illegal merchandise. The dogs themselves are happy, friendly dogs, if raised properly from puppyhood and not bred to be fighters, but in the wrong hands these dogs can be killers. And it's not the dogs' fault, but the humans who've raised and bred them that have given them bad reputations.
Before you even look for a breeder, check the laws in your neighborhood to see if you can even own one, and find out if there are restrictions on your property. Apartment dwellers should not buy a Pit Bull, because neighbors may become fearful and angry. Homeowners should check with their insurance companies to see if their coverage allows Pit Bull Terriers. If your area meets the requirements for ownership, you will need to be just as careful checking on breeders.
It is only common sense that you don't go to questionable neighborhoods to purchase your puppy. There are many dog-fighting groups out there, and they've become so cunning at what they do the police aren't able to catch them. These dogs are bred for their fight gene, and only the tough survive. Reputable breeders breed only the friendliest dogs, that have no tendencies to attack.
If you are determined to get a registered American Pit Bull Terrier, you will have to contact the UKC, which is a European registry. These dogs shown at UKC clubs are friendly and outgoing. Well-bred and socialized, they are a wonderful family pet. Beware of breeders who say they have an AKC registered Pit Bull, because there is no such animal.
With the above in mind, when visiting a breeder, ask to see the puppies' parents. See if they are friendly and outgoing. Check their bodies for scars and old wounds. This could mean they've been fought. Check to see if the puppies wag their tails, come up to you willingly, and don't act fearful or shy.
If you are looking for a pit bull as a guard dog, to be macho, or have aspirations of owning the neighborhood tough dog, please reconsider. Because of the bad publicity these dogs have received over the past ten years, you will only be asking for trouble. If you purchase a puppy and plan to have a tough dog, the chances are good that you won't have the dog for long. One growl or snarl and the dog will be labeled trouble. You may be asked to move, remove the dog from your premises, or have it put to sleep. Your city or town ordinance may prohibit pit bulls.
American Pit Bull Terriers can be lovely companions, friendly and amicable, with marvelous personalities. However, because of the stigma of today's society, a panting, "smiling" dog could be looked at as a snarling, leering menace. People will avoid you and your dog, afraid and worried. Ask yourself why you really want this dog before actively going out and seeking a breeder. When you find a breeder, ask as many questions as you can think of, and request literature to educate you on raising a happy, healthy pet. Unless you are looking for a show dog, a reputable breeder will ask you to sign a paper promising to have the dog neutered when it's old enough so that you won't be adding to the already overpopulated Pit Bull population.
