Thank you. She is on baytril.Hi and welcome
It doesn't look like a classic cheilitis. Could it just be something dried sticking to the side of the mouth?
Whether cheilitis is bacterial, fungal or microbial depends on what kind germ gets through tiny cracks in the skin of the lips that are generally caused by too much fruit acidity in the diet (including tomatoes).
What antibiotic is your piggy on?
Not sure how to treat my Mango
It does look that way in the pic but I think it must be food or a shadow because there’s nothing there currently on that sideShe seems to have it on both sides of the mouth?
