my dogs stink. but so does the price of dog shampoo. I know you can't use regular people shampoo because the pH is wrong for their skin and hair, but I am looking for information and/or a recipe for a replacement- anyone have any info on using mild household soaps (Ivory, Castile) to make dog shampoo? I mean, it has to be made of something, right?

Plus, I am allergic to perfumes, so this would help me two ways.

thanks!
