Make sure your puppy has alot of toys to chew on. Beef tendon sticks, rawhide, cow hooves, or pig ears are also good depending on the dog. Puppies need lots of good stuff to chew on so they will leave our stuff alone. Make sure to keep all dangerous things out of reach. They also make a No Chew spray to spray on items so they won't chew. It has a bitter taste. It's just a phase, be patient and buy lots of treats. Happy chewing!
Dogs don't immediately know what is and isn't allowed to be chewed. Give him toys, and when he plays with a ball, say "Good ball!!!". Crate him when he can't be supervised to protect HIM and your belongings!
Yep, make sure he has lots of his own chews and needs regular exercise to prevent him from getting bored. Don't leave him at home alone for more than 4-5 hrs. He could be damaging your things out of frustration and stress.
