I have a 9-month old Boxer who has become a holy terror. Last week she broke through the back fence (which is our neighbors'
;) and ran away. My lab mix followed her and he was lost for almost 24 hours. Now she is constantly trying to dig her way out along that back fence. It has gotten to the point where I can't leave them out at all - even for 20 minutes while I try to clean the house - becase she is digging. To make matters worse, she has taught Milo how to dig. We buried poo from all three dogs and she merely moved it aside and kept digging. Then I got smart and laid concrete slabs at the base of the fence where she was digging, and she just found someplace else to dig. The one time I actually caught them doing it, I spanked them, but must of the time I don't see it, so I can't spank them. I really need to get a handle on this now. She has chew toys, bones, I play catch with her, she used to go to obedience every week. I keep them busy. What could be causing this, and how do I stop it? She is destroying the neighbor's property, and I DEFINATELY can't have that. PLEASE HELP!
