This dog toy toothbrush is designed to clean and freshen your dog's teeth. After adding your dog's favorite toothpaste or food to the slots, let your dog brush his own teeth and freshen his own breath. You will no longer be bothered by having to brush your dog's teeth. The dog toothbrush is soft enough to avoid damaging their gums, yet strong enough to withstand chewing. It can protect them from oral diseases.
