Dayton looks like he has a wound on the inside of his ear, likely from self trauma. Yeast infections in the ears are very itchy, so sometimes dogs will scratch their ears and cause additional trauma. I would keep the area clean with a mild soap and you can apply a topical triple antibiotic to the area. However if the area is not improving or especially if it is getting worse despite keeping it clean and him not scratching, I would recheck with your veterinarian to see if anything further needs to be done.
