I have a 3 yr old blue nose pit whose is friendly, loving and just all around awesome dog. I also have a lab/pit mix, who is around 6 yrs old. He has bitten before (only females). I have 2 crates, and seeing's how they dont get along, I have to rotate crate times, which sucks. I tried introducing them, but the mix tries to alpha dog the blue nose (even though blue nose is larger/beefier), and he gets a little agressive. I cant keep doing this with them. I love them both, but the blue nose is a nicer/easier going dog. I can walk them side by side, and as long as I keep a fast pace they dont bother eah other. Ive even had them sitting next to each other with out a leash ( because treats were involved, lol), and they didnt bother each other. Ive let them loose in my house together (breifly), and they just chase each other until the mix tries to get dominant. I dont want to put the mix down, but its looking like it might be the only option....... It makes me sad to think about it..... any help or advice from anyone who has similar experiences would be great. I dont have kids, I have dogs, and they are just about the only thing that brings joy into my life. Thank you for listening
