Manda99, I received a few red flag warning signals from your post. First was TWO MALE PITBULLS (the larger intact and approching his maturity). And Second, It doesn't sound like Pork Chop was ever properly SOCIALIZED as a puppy. This is very critical in developing proper skills to associate with other dogs.

You are doing the right thing with Smokey by enrolling him in class. The sooner the better. The first 16 weeks of a puppies life are the most critical in SOCIALIZATION. They learn more during this period than any other.

Since P.C. doesn't seem to have these skills and his owner shows no interest in working on training (or even being with her dog much from the sounds of it) I don't see any hope of him improving his Social skills unless you are willing to work with him. He sounds like he is a bit too aggressive with a 7 week old puppy to me and needs work immediately.

Personally, if it were me, I would get Smokey out of there and find a new roommate or place to live. I see problems with this older dog happening if he is not getting training or the attention he needs. Especially since he is a Pitbull. Pitbulls can be very loving and friendly (look at KayAnn's Simba who is part Pitbull) if they are SOCIALIZED and trained and shown loving affection. However, they can also be nasty and very aggressive without the correct attention. It sounds more like the latter to me.

Be patient with the house training with Smokey. Puppies do not have full control of their bladders until they are 12 weeks old. Are you crate training? Smokey and P.C. are not together when you are at work are they?

Rough play is a given with two dogs (especially when one is a pup) but it sounds like sometimes this gets pretty out of control. As Smokey gets older, P.C. may feel the need to defend his territory more. He should be neutered too!

You especially need to keep Smokey away from P.C. when he is eating and / or chewing a bone. He is probably very food aggressive already. If he is already stealing his toys and things when Smokey is only 7 weeks old, what will it be like when he is getting older and learning to stand up for his things.

I see one of two things happening in this situation.

1. Smokey will become very submissive to P.C. and will let him have anything he wants.
2. Smokey will not stand for P.C. being so pushy and dominant and a all out war will occur and at that point, I can not predict what will happen. This will probably not happen until Smokey starts to come into his maturity though.

I would be very cautious where P.C. is concerned. PERIOD!
