My little Raindrop does that. Not the biting part, but has a fit when I grab my keys and head for the door. She starts jumping around, and makes me feel bad that I am not taking her. I think it's because I was taking her all the time with me, and now when I know I am going places she cannot go, I have to say to her, NO Raindrop, you cannot go. She will jump up and down like she is trying to convince me. I think the biting part that your dog is doing, is just to get you to stay. |
