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.

Not Tough Enough
Color: Multicolour
Not as tough as Wilson’s. Easy to be chewed and busted by pet.
