Truman give all of his fan a great BIG puppy kiss

He is doing so wonderful! He was just at the groomer Friday and she actually had to trim his ears! Remember when I first brought him home his ears were like leather. They were hard, stiff and scaly. Now they both have fully regrown hair.
I spoke to my vet about cutting his med back to every other day since his arthritis is so much better now. He does have several areas that the vet called warts that just do not seem to heal. I keep the hair in that area trimmed very short which is hard because he does not like to sit still. If anyone has any suggestions I would love a little advice how to get these areas to heal
