The ScrubBuster by Dexas helps make washing your dog at home a breeze! To use, simply unscrew the top silicone portion of the ScrubBuster. Fill the silicone bulb with the dog shampoo of our choice (not included), and replace the top portion. Turn the bristles towards your dog, and gently press the silicone bulb to dispense dog shampoo and massage your dog at the same time. The gentle silicone bristles dispense dog shampoo, and are long enough to reach through fur to your dog's skin- for a comfortable and efficient wash. When not in use, simply store the ScrubBuster upside down to keep shampoo contents in the ScrubBuster for the next use. Proudly designed by Dexas, a Texas based company that has created innovative and industry leading pet care and pet travel products. The only scrubber you'll ever need!
