My puppy has flaky skin. Does anyone know of anything that may help that?

Omega fatty acids and vitamin E are great for dry skin and can also help relieve joint pain from arthritis. Also, upgrading to a better quality food may help. If your puppy is already on a quality food (hint, if you can buy it at the grocery store it's a low quality food) then you may need to change to a different protein source as allergies can cause flaky skin.

Over bathing since dogs don't need baths, take it to a vet for a proper diagnosis/treatment.
