Hi everybody! Can anyone help me with the following problem? I have a 3 year old dog (girl). two weeks ago I bought a puppy and thought they would get along well. In fact, they were. The older dog used to play with the puppy, licked its ears. Everything was just great. But a week ago the older dog started her periods and meybe beacuse of this became aggressive...or maybe it is jealous..Yesterday it bit the puppy on its ear...Now they live in separate rooms. I have no idea what to do! I want them live in piece...
