Dont let the picture fool you, these are one of my favorite interactive trainers/toys.These egg-shaped critters may look soft, but they’re hard enough to stand up to the most aggressive chewers! The secret of their surprising sturdiness is a thick, durable rubber shell under their soft plush exterior. Includes a loud squeaker “yolk” for extra fun! We love these for training purposes. We are big waterfowl hunters, these are big for the dogs mouth , teaches them to hold on tight but soft. Made by the KYJEN company.
