Lasted my dog hours and hours, endless entertainment and seems to have made her teeth cleaner. No adverse side effects on her stomach. A lot larger than expected!

We purchased on advice as our Dobermann is a real chewers. As an active puppy he needs a distraction whilst out for coffee or in a beer garden. He really likes it but it's not quite as long lasting ( for his breed) as we would prefer. It's great that its natural and part of his meals.
