I wanted a recipe that would discourage the fleas and soothe my dog's itchy skin. The only recipes I could find online used icky things like dish soap, which will dry a dog's skin. I see this as a base idea for a dog (and people) shampoo. If you don't have some ingredients or think others would be better, switch it around. A few notes: Be sure to grind the oatmeal very well, otherwise you'll be picking out little pieces from your dog's coat. The turmeric is a very healthy, healing herb. However, it's also a bit of a dye. I didn't see this as a problem since both my dog and I have brownish blonde hair. Any lightening or reddening the turmeric did was a plus. But you may not like this. Both the essential oils are known to be good for the coat and bad for fleas. You may want another oil as well as or instead of for a different smell or different effects.
