Having a look, I know its an old thread but think my lad is big. He has a covering on his ribs but mostly can't see them due to his incredibly thick double coat. Anyways I was amazed at the remarkable difference between him and his sister whom we also have. She is very svelte with a much finer shorter coat. She is 24 inches and 28 kg... He is 26 inches and 42kg.... So much loose skin still to be filled! =-O
