When we first noticed the dandruff we though it was stress, as this sometimes would cause flaking on his coat. But then the dandruff  and flaking just kept getting worse, and now he has very dry skin and is always itching his paws and and belly. Do you think we are looking at dog dandruff, or perhaps skin allergies?

Assuming that it is dandruff on his skin, what treatment, or diet would be best. Is there a lotion or shampoo that we can use to clear it up?

Thanks so much!!! Jamie!
