Beware commercial dog treats. My Shiba Inu mix developed a strange rash, with dropped fur and skin irritation in a patch about 2 inches wide. Eventually I traced it back to a recent manufacturing change in his usual before-bedtime chew treat. He had never had any kind of rash like this before, but it persisted. When I figured out what it might be and stopped the treat, the skin irritation finally quickly calmed down and now it has healed completely. I don't trust any of those treats- full of strange chemicals.
