My little Morkie Belle is a terrible toy destroyer! She does have a Kong that I put a pressed bone in and it helps her hang on to the bone to chew but I take the bone and Kong away when I am not watching her. When we got Belle we bought all these cute stuffed toys. Little by little Belle has destroyed every one. She zones in on one spot and chews until she hits stuffing.... Yeah Belle's favorite. If there is no stuffing, she eats the ears, nose or feet off. She was vomiting one morning and out came this strange looking blue slimy thing. Looking closer at it I discovered it was the ear off her new twist puppy. I have a whole bag of toys that didn't pass the chew test. Belle has almost no toys left. Anyone that knows any really tough toys I would love to hear what they are.
