Acne is a benign disorder that typically lasts for a short duration. It occurs when the hair follicles become irritated. Dogs with short coats such as Boxers, Bulldogs, and Rottweilers are more likely to have this condition. Dogs may also experience intense pain and itching.
Acne tends to come on at puberty, from five to eight months of age. Typically it is gone by the time the dog reaches one year of age.
