This is one silly boy. Mister has been about perfect. He crates well,eats well and loves,just loves to play with his stuffies. He has had no accidents in the house and sleeps all the way through the night in my bedroom. He gets along fine with all the other greys in my house but is not cat or small dog safe. He is a very happy and friendly guy. Mister has a very fun personality. My vet said that he wags his tail more than any dog he has seen. This is one sweet big guy.
