Callie was prescribed the Omega 3 fatty acid oil because her skin was soooooo dry. That has helped tremendously. I bathe them with Banana Oatmeal Dog Shampoo. It has a chihuahua on the front.

It says it soothes dry, flaky skin.
Annabelle actually has the opposite problem. She is greasy. :? I don't use this shampoo on her and she doesn't get the Omega 3 fatty acid oil on her food. I actually bathe her with Dawn Dishwashing liquid in the Wildflower Medley scent.

It works really well on her since it cuts grease. LOL!
