buck was an amazing dog, he understood everything we said, and loved us all.rob was his favorite. they spent so much time hiking and fishing together. buck wouldn't sleep at night until he checked the bedrooms and made sure the kids were there and all right, after that he would come and check me and rob and go to sleep.there is no way to explain this dog. someone once asked us if we were sure he were a dog and not one of our hairy kids. some dogs are just more intelligent than others, and he was one of them.the day we had to have him go to heaven will always be in my memory,
