Thanks, now I do remember that. I kept thinking I needed a powder but my mind was running through stuff in my home medical supply cabinet but nothing fit the bill. I had a spray antiseptic for cows but I wasn't worried about that. Those long velvet Weim ears are hard to deal with when a frightened 135 lb dog is on the other end. He's curled in a chair sleeping. He likes to go out at 2:00 but when it's close to zero he may remember and skip it. I hope.
