My son is thinking of getting an American Pocket Bully. This is after owning an American Staffordshire Terrier who is probably going to have to be PTS after biting his wife. He was being managed for his DA and HA tendencies but this time he bit one of his family. Anyhow, my son wants to get another dog if this is what he has to do. He was talking about the Pocket Bully. I am not familiar with the breed. I know he wants a dog that he can take out and about without worrying, but not a dog that requires a lot of exercise. Has to be good with kids too. Any opinions?
