My dog has some patches of skin that are dry and irritated and some of his hair is falling out.He has lost a lot of weight despite the fact that he eats well every day. I have tried creams and ointments on the areas and it has not helped. I have been feeding him extra and he still keeps losing weight. What could be wrong with him.
The clinical signs you describe warrants a vet visit and a blood test. The weight loss worries me. I can not make a diagnosis without a physical exam. vetcrae
