Q. My 11 year old Chi has these ridges across his nose that are hard and dry sort of look like a wart, should I worry?
JESSICA L DESROSIERS
A. Dry patches or calluses on the nose are very common in pets and can occur if they enjoy digging outdoors or sometimes just digging around the house. They can appear as areas of minor hair loss where the nose meets the fur, and can also have a hardened, patchy appearance. These are normal and can sometimes come and go on their own.
However, if the patch appears to be spreading, or is bothersome, that is not typical of a callus. If the area is itchy, red or appears to have an open sore or wound, it may indicate an issue with the skin or a growth that is abnormal. Keeping the area clean and dry with a washcloth may help with minor irritation, while more serious or prolonged irritation should be looked at by your vet.
