Why does my dog have open sores at the corners of his mouth?

Question

My dog has an open sore either side of his mouth? What could this be. Pet's info: Dog | Scottish Terrier | Male | neutered

This presentation could be due to a localized spot of skin infection (likely to be caused by bacteria or fungal). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching.
