First, thanks for all the tips and emails with suggestions on Lola's issues. However this evening the mystery of her behaviors may have been solved.
Her last home had taken her to a vet in another town for a bladder infection. But it's not convenient for me to travel out of town for a vet, especially since I love the vet clinic here. Due to privacy laws, I can't get her info transferred. The other lady has to make the request. So I called her tonight to ask her to do this before Friday. She wasn't home but her husband answered. He said he'd give his wife the message and asked me how the little pup was doing. Sweet, right? Just wait......
I told him all the good things like how smart she is and all the new commands she is learning. But then I told him the nipping and biting was a real problem. My hands and ankles are like pin cushions. He cleared his throat and began confessing
"Well Dear, that might be my fault". He told me he used to play rough with her, let her chew on his "tough old hands and feet", tease her with a sock, play tug of war etc. Grrrrrrrrr
