I am not myself an apbt owner but I know numerous people who do and I also know a few breeders, and believe me I love the breed. Every one of their dogs are great and well behaved. But you must remember the inate temperment of these dogs. For example A guy I know had two female pitts that he raised from puppies right along side each other and both were great. However about three years down the road he came home to find both bloody and nearly dead from fighting. It could just be one time over a little thing but it could always happen. so it might be a good idea to keep them apart when you are not home. Now I am not saying that pitts are mean at all. In fact I almost adopted one but my boxer just would not get along with it. All I am saying is that you can take the dog out of the fight but you may not be able to take all of the fight out of the dog. And personally for both dogs health and safety I don't think I would wan't to test it. It is just bred in to them, both boxers and pitts are a dominant breeds and sometimes heads just clash as with any other dogs. The difference here is if this does happen it could result in severe injury. It's not like having a jack russell and a dachsund that don't get along. I hope everything works out and I didn't step on any toes if I did I apologize. I just want to restate that pitts are great dogs and do make excellent pets when raised accordingly.
