Unsafe and absolutely garbage
Color: Yellow Frisbee, Size: Large
If I could give this zero stars, I would. My dog had it for approximately two minutes of playtime, I didn’t even get to throw it, and it already had holes in it. He wasn’t chewing it or playing aggressively. He simply had it folded in half in his mouth and it tore. This toy is not safe for dogs.

Perfect ball for my Chihuahua
Color: Multi Meteor Ball, Size: Small
My dog is a Chihuahua. The small size is perfect for her. She loves chewing on the ball and loves the crackling noise from the material inside. I love that it is strong enough, she cannot tear it apart or is she able to remove the material inside. Perfect for her.

Best toy for our dogs!
Color: Yellow Frisbee, Size: Large
These are great for our labs. They love to fetch and play in the back yard. Loved how sturdy these have been the last few days. The material is tough enough to withstand our boys.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off.
One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again.
If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
