Thank you for submitting your question regarding Cola. She may have a mild skin infection along her lip margin there. Try your best to keep the area clean and dry for her. Wipe away any food or drool. If it is not looking better within a few more days, she will need to see her veterinarian. She may need to medication to help the skin heal. You can also discuss the possibility of an allergy to something in her diet. I hope this information helps!
