When we got Teddy Bumpkins, Barney was FURIOUS about it. He beat Teddy up immediately. Daisy also was disinterested in Teddy - avoided him like the plague.

I called in a trainer to help - she suggested I separate the dogs and use supervised visits. The other thing she stressed was to make sure that good things happened every time that the new dog was in the room with the old dog.... so that the old dog would start to think "hmm good stuff happens when new guy is around" -- this worked like a charm. We kept all three dogs moving about the kitchen for treats, using really upbeat voices and I took all toys and possessions out of the room because Barney would ferociously guard his resources from "the intruder" and I introduced the toys slowly when they all were around. Teddy slept in his own room by himself for a while, then we moved him in his crate to the same room but he was in his crate. Barney eventually did not mind him being in the room in his crate but got all pissy when Teddy came out. So we really had to monitor things. I kept Teddy tethered to me on a loose leash as well because he was using inappropriate puppy behaviors on Barney who was very intolerant. Like snapping his jaws at barney (not too smart Teddy!).

Your dog will hopefully come around if you do some of these tips. I never thought Barney would and I was worried that poor Teddy would never be accepted. It took Daisy about 3 or 4 months to accept Teddy but it took Barney almost 6 months. He still wont really play with Teddy but he does clean his ears and wrestle with him on occasion so he does accept him.

It is hard but your consistency in making GOOD THINGS HAPPEN WHEN THE INTRUDER is around will hopefully help.

Good luck!
