he does have suck a wide chest, and his tail is nothing like the beagles tails i have sen, it looks just like you sweet boys tail...only a shorter version!..lol!!!...when we got him form his previous owners he was sooooo FAT..he is still kind of on the chunky side...he has lost a few pound..but i dont think he is going to loose much more...he is one solid dog...very muscular, his chest is very wide even though his is smaller, he wears a large harness due to the width of his chest! What are Treeing Walker Coonhounds like???..they are very beautiful dogs!
