The sturdy silicone bristles gently work through a dog’s coat and massage and clean the skin, too.The ScrubBuster holds pet shampoo inside so it is easy to get the suds where you need them. Just twist off the retainer rings to disassemble ScrubBuster for easy cleaning. After the bath, the ScrubBuster dog brush can be stored upside down to keep the remaining shampoo inside until your dog’s next bath.
