Our male dobe and terrier mix (Killian and Buddy) chewd up my new recliner after only having it one month!!!!! got it recovered and 3 months later I came home to foam, foam, and more foam!!!!! That's when we decided to keep them in one room during the day and blocked them in with a baby gate. That didn't last long because we came home to DRYWALL all over and they learned to go potty on the drywall like it was a great idea!!!!! so, we finally got crates (killian passed away in march) and Buddy has no problem with chewing anymore. he doesn't even fuss about going in there. Our new puppies like to chew and we put wet rolled up wash cloths in the freezer for about an hour or so and they go bonkers over them. Must feel good on their teefers!!!!
