Highly entertained golden retriever!
Color: Green, Size: Large (3.0 in, Pack of 1), Color: Green, Size: Large (3.0 in, Pack of 1)
My golden retriever spends hours chasing this ball. Its erratic bounce pattern keeps him engaged and guessing where to chase the ball. It is durable and stands up to chewing well.

Great quality ball
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
The product is great no issues. It’s very durable. All of this brands products are strong and durable. The only reason I gave it a four star is I think my dogs prefer more the blue round balls. So that being said, I won’t buy these anymore, but they love the blue ones whether they’re the recycled or not. Great company!

Unique bouncing

Pups Love
Color: Green, Size: Medium (2-1/2 in, (Pack of 1)), Color: Green, Size: Medium (2-1/2 in, (Pack of 1))
As you can see from the photo, my pup absolutely loves it! It’s the perfect size for him and for reference he’s 25 pounds. It’s got a nice weight to it, but it’s soft enough to be able to throw and not worry about damaging the walls. We just started playing with it today, but it seems very durable.

Fun for the first day, but just get the round balls.
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
These balls do work, but they bouncy pretty
much like a regular chuck it ball. They do NOT fit in the chuck it handheld ball launcher, which makes them a pain to throw. The green color also makes them somewhat challenging to find when the grass is long.
That said, they do work as intended, and the dogs like them the same as all the other chuck it balls we own. As the person who had to throw them, my advice would be to just get the round balls that fit in the ball launcher.
Durability: 9/10 they hood together better than the traditional balls without the hole (that crack down the seam over time). These have yet to crack despite the same wear and tear.
Pros: durable, dogs like them, they do sink in water
Cons: green color, hard to fit in handheld ball launcher
