Tough, light weight, bouncy
Color: Yellow
Light weight but very tough and bouncy. My dogs don’t or can’t destroy these like they can tennis balls.

Perfect playtime ball
Color: Yellow
We’ve had these balls for almost a year and still have all of them. They’ve been to the lake, countless dog parks, and chewed on at home and they’re all still in perfect condition. Our dog is a 70lb English shepherd who’s no stranger to ruining balls

NOT for aggressive chewers!
Color: Yellow
My dog destroyed this ball within 10-15 minutes of use. He is a 65 lb German Shepherd. I do not recommend these balls for aggressive chewers.

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!
