Hi guest,
You do not say how old your dog is???? but, there is a doggie door bell on sale, though i dont know what its actually called, try Petplanet, it can be wall mounted, or set on the floor, adn the dog has to put a paw on it to set it off. Would that help you????
I currently have a pup who will go outside, if you catch him in time, but he also will run about outside for ages, then come in and toilet on the floor, so i know how frustrating it is!
