My 1 year old Doberman is eating every bed I buy. He eats terry cloth, Kleenex, paper towels, rocks, plastic sticks. Anything we drop on the floor if we can't grab it first. I broke a cup the other day and he was trying to get at that. Canvas bed, Kong bed. Holes in blankets and throws. I'm feeding Focus puppy food for large breeds. Thank God he doesn't chew on furniture. He weighs 85 pounds. he has loads of chew toys
