Dog recently started scratching at his ear. Noticed he had some wax in it so I cleaned it out a few weeks ago. Now I noticed him scratching at it again and the inside of the one is a little bloody from his nails I'm guessing. Cleaned it up a little with paper towel but I can tell its bothering him as he won't really let me check it out real good. Anything I can give him to ease the itching or something to clean it up good so it will heal up without him scratching at it?
