Honeygirl looks a lot like my Samson. He has dry skin too. I've been giving him Omega fatty acids in a capsule called VitaCoat Plus from Doctors Foster & Smith. When I got him 4 years ago or so, he had very little hair on his lower back and now it's much better. The vet thought he would never grow any at all. He doesn't scratch nearky as much as he did before.

My sister swears by Missing Link for her pugs.
