My dog is scratching, has red skin, and a sore. Is it infected?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 6 years and 5 months old | 155 lbs

My dog has been scratching more the past week. When bathing him, I did not see anything alarming like missing fun, but his abdomen was a little red. The following week i noticed a circular soar beneath the side of his ear and cleaned it with peroxide. The next day I applied more advantix. I do not see anymore sores, but I am still worried. Could this be something worse than tics? Also, a month or two ago he had heartworm treatment. He has not been outside as much since then and he sleeps indoors

This looks like an infected skin wound. It is possible that the wound was due to some sort of trauma or it could be because Noah was scratching. Either way, Noah will need oral antibiotics in order for this wound to heal. It is unlikely that any topical treatment alone will help.
