They're great if they're raised with them. The primary thing is they will almost definitely try to be the dominant dog. So if you bring a young male bull breed in with a established male of any other breed, there may be problems eventually.

I'm so worn out from reading the pure retarded comments from a couple of other boards that that's all I'm going to say. lol
when i got my APBT ive been very good with introducing her with as many people and dogs/animals as i can so hopefully she will not have any animal agression as she gets older. right now her two best dog friends are a 8lb poodle and my best friends 100lb american bull boxer mix. she will also lick you to deth like most amstfs and apbts will do haha
