Try increasing Vitamin E, which helps with healthy skin and coat.

Add this daily to the meal:
- finely chop one stick of broccoli (the fine head bits and a bit of stem; NOT a whole HEAD!)
- teaspoon of unsalted sunflower seeds
- one egg (the yolk is high in Vit. E). You can scramble it and put it over the broccoli, as some pups won't eat the broccoli, lol.

Not a cure, but should help.

When the dog is scratching, apply Gold Bond Extra strength medicated powder. This will alleviate the itch immediately, so the dog won't scratch till bleeding.
