its funny the things dogs decide to destroy isnt it?......... my last dog didnt make her way through the wall........ but she did EAT her way THROUGH THE FLOOR!!!
We were all surprised about that one
I think the "booties" is a great suggestion, the bitter apple thing is good but only if they are CHEWING the hole, otherwise the bitterapple spray will make the dog scratch at where you sprayed it specifically because it tasts bad and they want to get rid of it....
