We've never officially trained our dogs to stay in our yard. We don't have an invisible fence, or a fence of any kind except between the neighbours on our right side have on line of fencing.

We just spend so much time back there, and when we ARE back there, they we call them back if they start working their way into the neighbours yards.

But I don't suggest you try it with Buddy. He doesn't sound like the kind of dog that would you would be able to do that without an invisible fence.
