  We moved about four years ago and it was a brand new chain link fence we had put in. We watch them pretty closely. When potty training we go out with them every time. My dad put chicken wire on the two gates where that little gap between the fence and get is. Joey is the only one that digs and it's not at the fence it's because of a mole. If you just watch them and occasionally check your yard it's generally fine. It depends on the dog how long they learn. When you have treats and they know it they pick it up fast doing it without the treats can take them a bit longer.
