Hello and thanks for using Petco Pet Education Center, formerly Petcoach! Sometimes a dog may scratch around the mouth due to food allergies, environmental allergies or even autoimmune issues. If the area is red and irritated you may apply a thin layer of triple antibiotic ointment but Nobby is likely to just lick it off. She is at the age where food allergies may develop so you may wish to try a novel protein diet (generally will need a prescription diet to do this). If the itch continues I would suggest scheduling an examination with your veterinarian as oral antibiotics or other medications like corticosteroids or antihistamines may be needed.
