If you wanted to fix it without talking to them I'd put rocks or something in it. I wound up putting lattice all along the perimeter of our privacy fence and digging it a few inches into the ground. If your neighbors dogs aren't huge you could try that too.
I would mention to your neighbors the hole out of concern for both your dogs. You could say that sometimes you leave your gate open and you don't want their dogs to get through the hole and out your door. If they're good neighbors they'll fix it and appreciate your concern.
In the meantime you could get one of those steaks you put in the ground and only let him out on that. |
