This is our company's original patented product, which can be used as a water toy. Dogs chew on it to clean their teeth, maintain their oral hygiene, and play. The bottom of the toothbrush features a paw-shaped design that extends outwards, allowing pets to easily control the product with their front paws. The toy has a hollow design in the middle, with small holes on the outside that connect to the inside. This allows you to place pet toothpaste or treats inside the toothbrush, which will then flow out through the holes when the dog uses it.
