Not worth it
Very colorful and my poodle liked the ball. It didn’t last 1 week. Horrible quality and not worth the money. My dog destroyed ball as soon as I turned my back. Would return it if it was in a returnable condition

Great buy
Our dog is so happy about this. He loves chasing a ball. We also love the fact that it is collapsible and only 12 inches. We travel a lot so it’s perfect for that. I’m enclosing a movie. I did about it for Amazon.

Very disappointed
Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.

Tough & durable, but relatively light for throwing
Pattern Name: Tug Frisbee, Size: Large
This is the second one of these that I've ordered although to be honest, the first one is still very much intact and it was bought when my 3-yr old Shepweiler was still a young, but growing, pup! Tough & durable, yet light enough to be thrown (& caught), without much effort. It can also be used as a tug toy, as my other pup, a pit/boxer/"Heinz57" mix, loves to use it as.
