What about a medical adhesive remover...I have no idea if that is safe to use on his ears. After my nose surgery the doctor used this to get my cast off and it worked great. But you don't want this running down in his ear, maybe apply it with a Q-tip? http://www.amazon.com/Detachol-Adhesive-Remover-Flip-Bottle/dp/B0017LHS5Q
Again, I have no idea if this ok to use on dogs, maybe someone else will post soon.
