What is the best way to deal with skin flaking on my pet’s back? ceragyn?

Ceragyn products are not something I use. However, the online description indicates these are primarily for some type of infection. If this flakiness is due to infection the Ceragyn may be helpful. For general flaky skin we use a combination of nutritional supplementation with hemp oil, bathing with sebolux, and a topical oil treatment called essential 6 oils.
