Easy to grab and throw!
Size: Medium
Our puppy loves this ball, although it gets stuck on her teeth sometimes, but she gets it off just fine! Easy to play and throw. She has a blast catching it, too!

Keeps my dog happy
Size: Medium
This is a fun toy for our cavalier. It's pretty versatile in how you can use it, which I like because it allows me to change things up to keep my dog engaged. He's also an aggressive chewer and he hasn't destroyed it.

Good size and great bounce!
Size: Small
My 1 1/2 year old Cavapoo loves this toy. Very light weight ball that bounces off her paws when she reaches for it and then having to chase it further. Then she charges back with it for another chase when I throw it again.

THE BEST INDESTRUCTIBLE BALL
Size: Medium, Size: Medium
I bought this ball 6 months ago and feel obligated to come back all these months later to say how great it is! My Frenchie has killed every toy he’s ever had but not this ball! He absolutely loves this ball. It’s lightweight and can be used for both indoor and outdoor play and still looks brand new.
