You might want to keep an eye on it, though, it might be ear mites. I don't think it would be since Noah or Noel don't have them, and it's common (at least in our house) to have scratches in the ears that will draw blood, but if you notice tiny little black specs, or if he's scratching his ears a lot, you might want to ask the vet about the stuff to put in his ears for ear mites.
