A wide variety of dog shampoos are available in stores. But you might want to just make your own instead. I’ve found that I can easily create a dog shampoo from ingredients that most people have in their homes.

Mix 1 cup apple cider vinegar with 2 tablespoons lemon dish detergent. 

Add 2 tablespoons pure aloe vera. 
 Shake the bottle well. You may immediately use the shampoo or store it for future use.
