Okay, so here's the deal. My sister is moving in here with her dog, Jaz, in a few days. Cherokee is aggressive with other dogs, but has met Jaz before, and they were okay after a few minutes (though I did have her muzzled, just to make sure). Cherokee is very dominant and confrontational, Jaz is exactly the opposite. Cherokee could attack him, and he would most likely just sit there being terrified (which is really sad, but also really funny..Cherokee's a little 50 pound lab mix, and Jaz is an 85 pound pit bull).
Cherokee's been an only dog most of her life, but did live with my aunt's dog for a couple years when I first got her. They got along well most of the time, I think they had maybe 2 big fights in 2 years. Jaz lived with another dog recently, and while I don't think they ever really fought, my sister said he started getting more assertive towards the end. I'm really hoping that Jaz will be as submissive as I expect, and Cherokee will see that and be okay with him, but I'm not sure.
So basically I'm just looking for suggestions on how to make this a peaceful transition and life for both of them. I'm thinking we'll have some food issues, and maybe they should be fed in bedrooms, since neither of them have crates. Beyond that? I'm not sure what to do. I've never done this before. Anyone have advice?
