Help, need a good dog trainer, to help me stop my 6 year old Westie that has started going crazy when she sees squirrels , dogs, other animals outside. She is inside bitting chairs, curtains, blinds if closed. She has even tried to pull curtains off the wall. This new habit is getting worse. Other than this issue , she is well trained and a was a perfect pet. I am in White Marsh and will travel for a good trainer. Any other suggestions are welcome .
