Hey glenna, we are just the luckiest, I weight Rocky twice in the last two weeks, First at Pet Smart and he was 48 lbs, and my Vet the second time which showed him to be 47.7 pounds. He's just a year old!! and the previous owner told me he was the runt of the bunch, which I figured would probably make him the biggest when full grown. I do monitor his food intake closely and he's on Blue Buffalo Sensitive food diet. His previous owner had Cancer, very serious is what I was told, and Rocky was a wound up ball of energy, too much for him to handle in his health. So I adopted him, as his second owner, and he's definitely different from any other pet i've ever ownedā¦In a Good Way!!
