The ultimate softness for your pup! This bio degradable toothbrush is made from a wheat straw composite material. 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 hard and rigid, making the brushing process painful and difficult. The 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.
