The Dexas MudBuster is a new, innovative and easy way to rinse your dog’s dirty or muddy paws, before they track it all over the house! Using the MudBuster is easy: muddy paws go in, clean paws come out! To use, add a little water to the base of the Mud Buster. Then, insert the muddy paw, do the twist, dab the paw dry, and repeat for 3 more feet! The Mud Buster features an array of soft, gentle, thick silicone bristles inside an easy-to-grip tumbler. Designed to be gentle on your dog's paw, the silicone bristles will gently loosen mud and dirt, keeping the mess in the MudBuster and not in your home or car. The Mud Buster is great for trips to the park, hiking, running or even playing outside. The Small MudBuster is specially sized for small and toy breeds. BPA free!
