This silicone frisbee is the perfect toy for your pup! It's easy for dogs to bite and won't hurt their teeth. The float design ensures that it won't sink in water, so your pup can have hours of fun playing in the water. This product is safe, non-toxic, and non-polluting, making it ideal for outdoor training, exercise, and releasing pressure. It is a dog training toy, not a tooth grinding toy, when the dog is found to bite it should be stopped in time, otherwise easy to damage.
