We recently moved our dog pen into the backyard instead of the side yard. My pyr is having a bit of a hard time settling in because he can't see the street anymore (barked non stop so we decided to move his vision to our back yard). Well I arrive home today and he has got blood on his fur???!!?? I first look for the pup (8 week berner) and she is safe as a cute button...then I look back around and see that Marley has begun dismantling our 6 foot wood fence with his teeth!! I never thought he would try and chew his way out - nor did I think he could! Obviously we secured the whole bottom area thinking if he wanted to escape he would dig and there fore we lay cement slabs down! Now I am at a loss. I don't want him to hurt himself and also don't want him to destroy the whole fence! Any suggestions??
