The dry skin, or dandruff, is called seborrhea. It could just be from dry skin but it could also be due to an underlying disease. I suggest you bathe him with this special medicated shampoo 1-2x per week and use the same brand’s mousse in between bathing. Lather the shampoo, let it sit 10 minutes and then rinse. That contact time is important. ( https://www.allivet.com/p-6684-douxo-seborrhea-shampoo-for-dogs-and-cats.aspx?SearchTerm=Duoxo%20seb+Auto ) ( https://www.allivet.com/p-6678-douxo-seborrhea-mousse-for-dogs-and-cats-68-oz.aspx?SearchTerm=Duoxo%20sebo+Auto ) Also make sure he is on a high quality diet and use a skin and coat supplement like Missing Link for at least a few months. ( https://www.petco.com/shop/en/petcostore/product/the-missing-link-ultimate-skin-and-coat-supplement-for-dogs-283770?ref=dfs ) If all this doesn’t help then he needs a vet exam. Best wishes.

    This can be caused by various reasons such as fleas, mites ,fungal infection, bacterial infection and allergies. the first 4 needs to be ruled out before we start treating for allergies. in order to do that first de-flea Bailey with a high quality flea treatment such as advantage spot on, if it doesn't help - take him to the vet in order to check for/treat the other possibilities. If everything is ruled out, then an allergy treatment can be started. Usually an hypoallergenic food is a good way to start together with anti histamines. if it doesn't help - the best solution is a medication called Apoquel which treats allergies with great success and without side effects.
