One of the most sought after strains is the American Pit Bull Terrier (APBT). Breeders are putting this dog strain into more homes and are making a fortune. They love this dog and its progeny. Breeders and owners have noted the differences between the fighting dog strain and the American Pit Bull Terrier (APBT) as the fighting dog strain has somewhat abrasive coats and a different skull than the APBT. The fighting dog strain has a very luxurious coat and the tail of the fighting dog is docked shorter than the tail of the APBT. The pits of the APBT are not as pronounced as the ears of the show strain or the standards of the breed. And the AKC standard says that the tail of the fighting dog must be docked no longer than one half of the withers. The United States Dog Breeders Network, the breeders' organization, says that the American Pit Bull Terrier is the only one of the fighting dog breeds that has such a large vocabulary and variety of names. He is the bulldog, the progenitor of the boxer, and an ancestor of the English Bulldog. He is also the ancestor of the dog known as the American Staffordshire Terrier. Some breeders, however, claim that the American Pit Bull Terrier is a cross between the Old English Bulldog, the Old English Bulldog and the Bulldog. They program them as early as a year to a year and a half. In order to do the job of guarding and protecting have to be present and they will use aggressive behavior in the dog. They are very dominant and verbal. It is a aggressive looking dog and has been called the saddest and most pitiable of dogs. The dog is acutely sensitive to gentleness and friendly firmness. The American pit bull and the Old English Bulldog share a history of being overly aggressive. If you have two sweet dogs, you may be hard pressed to get both to cohabitate. Pit Bulls must be socialized early in their first year of life or they will become over protective, and Possibly dangerous. The disposition of the American Pit Bull Terrier is instinctive and inborn. They are Loyal, protective, and extremely violent dogs. In the dog, they have got the nickname "bully" and they will be aggressive if they think someone is going to gain advantage over them. No wonder they have gained such a bad reputation. Sadly the American Pit Bull Terrier is not improving in their treatment since the mid 1980's. They are banned in many countries and are being stolen on a regular basis. Do not wrongly diagnose a bad dog, it is a challenge to the owner/trainer to understand the mindset of the dog. One has to look at the dogs' breed background, personality, and how they were raised. It is the most effective way to help train the dog.
