PBRC is an outstanding organization. There are some very knowledgeable caring people in that group.
My mistake. They were bred to fight other dogs. I wrote "other animals, including dogs." However, they were also bred to have a high "prey" instinct which would include small animals other than dogs.
I don't lack compassion for the animal. I think its terrible that these dogs are tortured and used for fighting. What I do lack is compassion for the owner who does not recognize that an inherent trait of aggressiveness exists in these dogs. For that reason, they should be on a leash at all times, they should never be brought to dog parks, etc. Even the PBRC website states that adult pitbulls should not be taken to dog parks because they will "finish" a fight even if they do not initiate it.
