My small dog and 1 year old were getting along great for a while. It would make me a little nervous because DS would get super excited and smack her face as if he was clapping and her face was in the middle, but she handled it well. Now he's getting more rough with her (pulling her tail, grabbing her collar, etc)... and this morning she growled at him and it scared me. Has anyone run into this problem? I tried separating them, but she won't stop barking if she's in another room. She likes to be where her family is. Any tips/suggestions?
