Is she teething? Is it happening when nobody is home? I had this problem w/Princess when she was about 6/7 months old, my vet said it could be separation anxiety. Whenever I had to leave, I connected 2 x-pens together in the room they were in so she couldn't get to the wall. She eventually outgrew it.
When they're supervised, you can give them a chew toy or bully stick. |
