Supervise your dog! Think of your dog as a two-year-old child. Would you ever leave your toddler unsupervised? Your dog is an animal that can only be taught the “moment” he is chewing and destroying your possessions. Do not get angry at your dog after your things have been destroyed. He won’t understand discipline after the fact. The most effective way to keep your belongings in one piece is to keep them out of reach and out of sight (a good rule for toddlers too). Teaching your dog to go to its bed, using a crate, and building an outside dog run are tools that be used to contain your dog when you cannot supervise him. I recommend giving your dog three dog toys that he can play with when he’s alone.
