I have a 15 year old Pug. In May he started losing patches of hair, no bigger than the size of a quarter. There were a couple on his legs, one or two on his stomach and the last one has been on the under part of his neck. My vet has done all the blood work as well as skin scrapings and everything is normal. He gets better with meds, but as soon as we stop them, he gets another patch. These spots are not itchy. He is not bothered by them at all. I have an appointment with a dermatologist next week. However, I follow the life of an elderly pug on Facebook and I have noticed that he has several places on his underside with no hair. I was wondering if this could all be due to my pug’s age.
