Make Chews Irresistible

Redirection only sticks if the legal chew actually beats the couch, so make it win. Soak a rope toy in low-salt broth and freeze it, so the dog has to work to thaw out every tasty fiber. A smear of food frozen inside a hollow rubber toy does the same job: it pays out slowly and stays busy for ages, while a shoe just sits there being a shoe. The rule is simple: the approved chew should be the best thing in the room. Beat the furniture on flavor and effort, and your dog picks the toy on their own.
