I was looking for some helpful hints for my male shih tzu. He has a very oily coat and it gets such an odor. We have bathed him in lots of different remedies and its not better. He didnt use to be this way. He is nuetered and his age is 3 years old. He doesnt have any other sign or symptoms. Everything is normal other than his oily spelly skin and hair. I groom him myself so that I can take his hair pretty short. That helps alittle. HELP!!!!!!!!
