First off I am so for people getting shelter pets and how amazing it is to save a life! So totally for it.
I live in a house with 2 other girls. About 6 weeks ago I was hit by a drunk driver and the crash killed my amazing little 1.5 year old cockapoo. I am still grieving the lost of my baby boy but decided to open up my heart to a new pup named Millie! She is a mini labradoodle so only about 10lbs right now...
So 3 weeks after I got her my room mate decided to adopt a pit bull mix dog from a local shelter. He is sweet but plays VERY aggressively, is 40-50 lbs, and even though she was told he was potty trained is not. This has caused my puppy to go backwards with the potty training, she is constantly getting hurt, and the thing I am most concerned about is that she has changed from this sweet docile dog to aggressive and a biter. She loves biting now because that is what the other dog does to her (which I immediately punish for, but is still an issue).
I just am at a loss about what to do about it. Do I let them play fight until they finally chill, do I make them stop immediately until they stop trying? My room mate is also new to being a dog owner and is not disciplining well so this is another struggle.
All and any help/advice is appreciated!! I have never had an aggressive dog so I am so lost on how to deal with this.
