Why does fox poo smell so bad? What can they possibly eat that makes it so disgusting to us and so inviting to dogs? I thought Dudley was bad but Thomas is ten times worse and he can find it from 100 yards, home in and roll. Last night he came back with it down both front legs and all round his neck, underneath and on top. I thought I was going to be sick and actually told him to pack his bags as I'd had enough!
