Teaching the full stop

A bitter spray is an interruption, not an education. The first lick of Fooey! reliably ends a chewing session — the pet recoils, the sneaker survives — but what happens in the next thirty seconds decides whether the habit dies or just moves to a different shoe.

The full method has three beats. First, post the sign: coat the target object thoroughly, and every object in that category — one sprayed sneaker teaches a dog that this sneaker is cursed, while a sprayed shoe rack teaches him that shoes are cursed.

Second, offer the detour. The urge to chew does not evaporate because the couch turned bitter; it needs somewhere legal to land. Park an appealing chew toy within a step of the old crime scene. For teething puppies, cold and rubbery wins; for adult power-chewers, the toughest thing the pet store sells.

Third, reward the stop. The instant your pet backs off the sprayed object or picks the toy instead, mark it with praise or a treat. This is the beat most people skip, and it is the entire difference between a deterrent that works for a week and a habit that is actually gone.

Keep the spray schedule boring: reapply daily for the first week or two, because the bitters wear off faster than the memory forms. When you have seen a full week of the pet ignoring the old target, start stretching the interval. Most households retire the bottle to the cupboard within a month — which is exactly where a stop sign belongs once everyone has learned the intersection.
