This is our company's original patented product, which can be used as a water toy. The toy has a hollow interior design, which can hold treats or dog food to attract dogs to play. The food-dispensing holes are arranged horizontally, and double-layered dental cleaning fangs are designed on the sides of the food-dispensing holes. While the dog is using this product, it can better clean the dirt or tartar on the dog's teeth and protect the dog's oral health.
