If you do see your pup begin to squat in the house, make a loud, abrupt noise to startle him. (We avoid clapping since it is a great way to encourage your dog to come when called.) Something as simple as a slap on a nearby wall or table can be enough to startle and interrupt him. Then immediately rush him outside (cheerfully) and give him tons of praise and a treat for eliminating outdoors. Come back in, and put him in his crate for a moment while you clean up his accident.
