Does your dog have a problem picking up ordinary discs when they land rim down? Our Spindrifter Dog Discs have a rim on both sides, which make it easy for a dog to pick up any way they land! And the soft construction is easy on your dog’s teeth when catching out of the air. These discs are unbelievably durable. We have seen some that are over 10 years old and still flying! They are made with a dog safe, phthalate free vinyl.
