Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Size is perfect for tossing
Color: Multicolour
Great to toss for dogs. But if dog chews it much, they don't last long.

Durable and great color
Color: Orange, Color: Orange
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!
