I have 9 of these. One large can of dog food fills 9 treat balls. Freeze them for a few hours & they are ready for the dogs to enjoy. I have 3 golden retrievers who really look forward to treat ball time. It is a great way to occupy them for about 15-20 minutes. Great for keeping them calm when visitors arrive too. They like these much better than a stuffed Kong. These are easy to clean & easy to refill. Highly recommend.
Seems so simple--what can you ask of a ball? This one is better than just any old ball. Nice and bouncy. The treat hole is big but it worked for soft stuff in the bottom. Hope it's still around next summer for use in the pool.
