Buster will howl occassionally. It almost sounds like a cat yowl at times. The first time we heard it we were wondering if it even came out of Buster. We were laughing so hard I think he got upset we were making fun of him he gave a little harumpf and walked away. But he has done it a few times. It is really funny with the head tilt and when he starts there is no sound at first and then it builds..very cute...very funny. My own little mini wolf!
