Never pop balls
Color: White
These things are the best balls you can buy. My dog loves playing with them and chewing on them. And she has never popped one they are a great purchase if your dog usually pops other balls. These are solid and light weight

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.
