Technical term, I know, but he really has very red ear flaps. He's fine in himself, playful, eating well etc. He's scratching sometimes, but not more than usual I don't think. His ears don't smell bad (just dog ear-y). He is on noroclav for a bout of colitis (finishes the course on Tuesday). Could this be a reaction to the antibiotic? I only noticed it this evening. The rest of his skin seems a normal colour.
