Amazingly strong

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

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
