My Cody has allergies and is always scratching under his nose, under the nose is red from the scratching and he has hair loss, it looks exactly like your dog. Cody is on med. Apoquel for 6 weeks now, he has a vet appt. this week, vet may have in change dosage, I never had a dog with allergies so I don't know what the process is. Google "canine ringworm pictures" does that look like what your dog has? it will also give symptoms of ring worm. Allergies come from environment, pollen, dust in the house, if you use air freshener in your house, what you use to clean your floors, can be many things. Your dog may be allergic to his food. You need to speak to your vet about allergies.
