Pet's info: Dog | Boston Terrier | Male | neutered | 8 years and 3 months old | 20 lbs
My 8 year old Boston terrier has some round patches on his belly. There are some raised bumps as well. Is this a skin allergy or something more?

Hi and thanks for your request. These are epidermal collarettes.; they are 'footprints' of a vesicular or pustular lesion. They are therefore a common lesion type in canine pyoderma, which is a type of superficial skin infection. An allergy could be present, but the signs are solely compatible with an infection. Disinfection can be provided with hibiscrub diluted with water 1:10 twice daily. Make sure to rinse off the solution and leave the skin dry. The signs should resolve in the next 4-5 days, if not a check up will be needed.
