Haha. Bella is so clever, I wish mine did that! It would save me having to cut them! Willow doesn't seem overly clean or overly dirty. Mylo is the same as you guys mentioned though. He does not eat, put his nose in or roll in poo. He avoids puddles and dirt on our walks. He tries to avoid touching his raw meat with his paws at all costs and then he will immediately wipe his mouth clean afterwards or if he just takes a break. He cleans his paws and when I used to let him in my bed at night he would lick his paws thoroughly before he would settle down and sleep. He also had a 'Klingon' the other day and he looked like a dog possessed trying to get rid of it before I could get some tissue to his backside!
