All of our WildWash PRO shampoos have a 32 to 1 dillution rate, ensuring they last a very long time. With the exact shampoo to water ratio, we have built a WildWash Mixing Bottle. To the shampoo fiil line, simply fill with WildWash Shampoo and then add water to the water fill line and mix. Pull up the nozzle and cover your pet with the mix, then lather, wash and rinse. This makes bath time easy, quick and straight forward for us and our furry friends.
