This is a 12oz refill for the Hound Suds sprayer in a spout pouch type container. It is a concentrated product requiring dilution before use. This will refill your Me&T 8oz. sprayer 3 or 4 times depending on the dilution you like to ue for your particular dog. Thicker coats will require a more concentrated shampoo while thinner coats can use a more diluted product. Fill the sprayer with 1-2" of concentrate then fill the rest of the way with water.
