I got a 1year old great dane..who seems when I leave the house has a chewing problem. I think alot of its out of revenge. I just left the house for 15minutes..and came home to a old phone chewed up..toilet roll/paper chewed up.. and plastic water bottle chewed up. I have bought him expensive chew toys..rawhide bones..(which he just devours) My next step is a muzzle. I bought one but when I put it on him it breaks my heart to see how he acts. Is there any other way to get him to stop this..other than buying him a dog crate?
