E-mail me, or respond in this thread with a description of the dogs, the fence, and what they are doing to get out. We’ll do a cost/benefit analysis.

The Fence is a chain-linked fence and the ground is concrete.
Well, I have an 80-90lb dog that had figure out how to open a simple latch on the gate. I a leash on the latch to prevent the dog from opening it. Then the dog tried totear a hole in the chain link fence. Sorry if I am not being clear but I don’t have any pictures to show you.
