So I just got a new puppy two days ago. She has a past where she was played too rough with by other dogs. She doesn't like other dogs until she is around them more and starts to play with them. But she HATES our yellow lab puppy. She growls and barks at him and even goes after him if he gets near me and walks in my room. I don't know what to do because my boyfriend is freaking out on me because she's doing it and he's even starting to throw things at her. I don't know what to do to help them bond more. Our yellow lab wants to be friends with her but she doesn't like him much. What could I do!?
