JW Mega Egg Doy Toy JW Pet products use hands on product research and development to develop intelligent product designs that make the lives of pets and pet parents easier. Keep your dog busy for hours with JWs Mega Eggs. Great for solo playtime or fetch, the egg-shaped design makes it nearly impossible for dogs to get a solid grip with their paws or mouth, causing the Mega Egg to shoot out from under them, creating an endless game of chase! The constant, erratic motion will keep your dog entertained while engaging their natural hunting and chasing instincts at the same time. Available in three sizes, JW Mega Eggs are made from durable, non-toxic plastic designed to resist punctures and are built to last.
