It is a shame that they have been used for this type of activity, as most people are now afraid of them because they are known as very aggressive dogs. A fighting pit bull is a dog that spends his life in training to fight against other dogs and most of the time they end up killing each other. Even worse some people don't finish this training and that's when they turn aggressive against adults, children, or at any other animal.

Most people still don't trust them, as there have been a lot of cases where they have killed not just other dogs, but people. These aggressive characteristics are not common and have given this dog breed a bad name.

However, many of them have been loyal family pets for years.
Some states have laws against having Pit Bull dogs in homes, apartments or having them walking without the right equipment. 
Even when most of them are great dogs with the proper training, there are still people who promote the aggressive instincts giving a bad name to this breed.
