i was gonna say 'ringworm', but ringworm is on the body, not the nose. any way, ringworm is patchy, irritated, and red skin, but not to be confused with a rash. my doxie stud, sam, had one of those on his nose and it went away in a few days. if your dogs (could be some sort of erosion) dosnt go away in a few days, i suggest you look it up on the internet, take him/her to the vet, put some salve(but ask the vet first). if i sound like a 'know-it-all', sorry, just giving some advise
