This is our company's original patented product, which can be used as a water toy. It is a toy set that combines two olive-shaped treat-dispensing balls and one serrated treat stick, which are two kinds of dog chew toys. It combines multiple functions such as interaction, treat dispensing, and chewing. It can also be used as a training ball to train the dog's agility. It can be used by the dog to play by itself, or it can be used by the owner to interact with the pet and enhance the bond between the owner and the dog.
