Amazingly strong
Color: White
My dog loves them, I was buying normal tennis balls but he was chewing them and splitting them these don’t break but they deteriorate if they get left outside 100% recommend just keep that in mind

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

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
