Poor boy, at least you have figured out what it is and can get the meds to help him. He has such gentle eyes, and is overall just such a handsome pup! Good luck to him in receiving his CGC, he will make a great therapy dog... everyone will love him just as much as all of us do.
Miles and Katy are adorable, as well. I think I'm a sucker for Miles, I just want to give him a big hug! ;D
