How do you trim the fur under the tail for sanitary reasons? Lani had some poop stuck in her fur today that irritated her bottom something terrible. The skin is very red and she keeps licking and whinning. I have used some vasaline to help sooth the skin. It seemed to have worked for a while but now she is just laying and whinning and licking herself (almost frantically!) Any other suggestions? I feel so bad for her.
