Cleo loves to lick everyone's face, but other than the occasional obsession with her crotch, i hadn't noticed this problem before. Earlier this week, she started licking the top of one of her front paws. I wondered if she stepped in something that irritated her but there was nothing visible. There was no change in her diet or anything else I'm aware of. I have offered her chews that she likes, to give her something else to do with her mouth, but she eventually goes back to the paw. i have to think something there is bothering her. Now, after a few days, i noticed she has a small raw spot on top of one of her toes. Obviously i don't want this to continue! Any advice on stopping it and on protecting the part of her foot that is irritated?
