Bo loves to chew on just about anything he can get (mostly me!
). He also is attracted to some wood mulch that is around the trees in our yard. A word of caution though. I never let him chew on the wood if I can help it. Wood is extremely hard on their stomach and could cause a tear either there or in their esophagus. I'm not a vet but my 7 year old schnauzer chewed wood when he was a puppy and vomited a lot of blood and has had a delicate stomach ever since and he is on a special diet because of it. I would definately keep them away from the wood if at all possible.
