Just like humans, your furry friend"s overall health and well-being will be improved with regular oral care. Feeding dry food and providing crunchy treats will allow for the passive cleaning of your dog"s teeth, but the best way to ensure optimum oral health is actively brushing your dog"s teeth on a regular basis. The design of the brush is an important factor too and the triple head design of this toothbrush is small and easy to use. The three-sided 45-degree angled bristles actually clean the inside, outside and top of your dog"s teeth at the same time.
