I had the same problem - all I can say is keep a good eye on your fence - we had a pitt move in next door (now it's gone) but I had to go reinforce my fence (not pretty!)
The pitt and the normally nice dog chewed thru the little spy holes that were there - I was so worried my girls would get hurt... I slapped every kind of board and brace I could find ...now I have a terrible looking fence on one side but nothing will get thru it - they had fun racing the fence but I know a larger dog could easily hurt them playing or not |
