The ultimate softness for your pup! This toothbrush is made from a wheat straw composite upcycled bioplastic. It has over 10,000 silky PBT bristles to provide the deepest cleaning action while yet gentle on your dogs sensitive gums.This brush comes in a breathable container for easy storage. Most dog toothbrushes are made with hard rigid nylon bristles, making the brushing process painful and difficult. Our Puppy Polisher brush makes the process painless yet effective in plaque and debris removal due to the ultra fine PBT bristles.During production, injection molding fuses bristles to our brush head, eliminating extra space where bacteria can hide and grow. Brushes are UV treated for sanitation. Mini size also available for small dogs. Comes with J hook for slat wall hanging. Can also be used with display stand. Made with international parts, designed with love in Canada.
