All of our WildWash Shampoos have a dilution rate of 32 to 1. We have designed a WildWash Mixing Bottle to show the exact shampoo to water ratio. Just add WildWash Shampoo to the shampoo fill line, add warm water to the water fill line and mix. Wet horse or dog, then use the diluted mixture from the bottle. This makes washing quick and easy with no mess and no wastage Ref: UTBZ1288
