i'm going through it with the 2nd puppy in a year. we just make sure he has too many things to chew on. bottles, boxes, bully sticks, bones, hooves, antlers, empty paper towel rolls, pig ears, pork skins and whatnot and keep things he can't chew on out of reach or take anything else he can't chew on away when he gets it. place was a mess for a while. he's 15 weeks now and has for the most part knows what he can chew on or not. our last puppy kept trying to chew this one spot or the wall on a corner and No Chew spray on there worked pretty good.
