I’m so happy with these orange tennis balls! They’re the perfect size for Roxy’s ball launcher, and the bright orange color makes them super easy to find—no more losing them in the grass! Roxy goes wild for them, and they’re holding up really well even with all her chomping and fetching. If you’re looking for fun, durable balls that stand out, these are a winner!

Cheap but good for what we do!

Color: Dark Blue

I wouldn't play tennis with them -- not that quality. However, we use a chuck-it thrower for our pooch and it's the perfect ball. When she's rips them open it's no big loss. Chinese.

Good Quality but Lose Bounce Over Time

Color: Yellow

Solid tennis balls overall, but after a couple of weeks of daily use they start losing pressure. Still a great deal for casual games or practice.

My dogs are obsessed with these

Color: Multicolour, Color: Multicolour

Red, Molly, and Karma are absolutely obsessed with these tennis balls. They’re bright and easy to spot outside in the grass, hold up surprisingly well during rough play, and don’t immediately shred apart like a lot of dog toys do. Great for fetch and everyday play time — definitely a favorite in our house.
