Misha, while homeopathy can help him, this is decidedly not "what's that remedy?" time. It's time to hire a professional homeopathic vet, one who does mostly or only homeopathy and can help you by telephone. This will take skill, more than one remedy to cure him, and treating the "whole dog" until he's cured. Nothing DIY about this situation.
I've got a list of colleagues who can help in my free Homeopathy Short Course, under the Recommended Resources towards the end. Don't pass go, get in there and hire a pro.
