When Jezebel's nails get to long she will nibble on her feet until I cut them. Also, Olivia has dry skin that flakes despite how I try and treat the problem. You mentioned Wellness pet food. My girls eat Wellness dry and canned. I'm wondering if this has anything to do with it? Jezebel does not have dry skin, but she has always been really oily. I would hate to change food because of every type I've researched, Wellness seems the best!
