entails...[oops, baad pun!] Check out websites for dog skin supplements... One site is from a company I've known and used years ago for my horse {dont laugh}
.
FAQ's: skin & coat enhancing dog supplements. These guys have been around a long time and test all the products they sell. You'll probably not be surprised at some of the nutrient info-sounds very familiar. Like all mail order products, you mite get it cheaper at a local pet-mart or the vets considering S&H costs and all. I bet you will find the right combo! It hurts US to see our creatures unhapppy.

Hugs Billye & scritch those guys for me! - j
