We have 5 completely fenced acres that can't contain Max, a 17 month old neutered Weimaraner-lab mix. Whenever we let him out he diggs under the fence into the neighbor's yard to look for their dog. Each time we find the hole and cover it but he just moves to another spot and diggs under again. I've heard that putting rocks around the fence line or burying some of the fence underground would help but we have too much fence to do this. Hot wire or a shock system is hundreds of dollars and I don't want to shock him if I can avoid it. He loves to race around but we can't trust him to stay in the yard so his exercize has been limited lately.
We have another dog who never leaves the yard. Max has food, a playmate and lots of stuff to do in our yard so why does he keep leaving and how can we stop it?
Any suggestions would be appreciated.
