I got this ball for my dog so I could teach her how to play. I like that the ball is nontoxic and made with the thermoplastic rubber. The only problem I had was no instructions on how to get the food in the ball. Finally my husband figured it out. It was fun to see my dog roll the ball around and see the dry food come out. She didn't know what was going on at first. Now she enjoys the play time and treat time. Great interactive toy for developing skills and dogs getting exercise and erases boredom. The box even contained toothbrushes for doggies. How nice. Now she can roll the ball eat the treats and brush her teeth. Great item to purchase for dogs.
