The Indestructa is an indestructible ball! I have two dogs. One is a strong chewer. She tears a tennis ball up in minutes. Most dog toys do not stand a chance with her. The Indestructa has beat her. After a few days of both dogs jockeying for the ball and gnawing on it for hours, the ball looks like it did coming out of the Amazon box. I think part of this is due to the size. The ball is somewhere between a baseball and softball in size. This is a good to toy to have in our arsenal!
