Keeps our pups busy
Color: Blue/Green, Size: 2.75 in
Approx. the size of a tennis ball, perfect for our 2 doxies, keeps them happily occupied. Appear to be nice quality and will last a while.

A must have.
Color: Yellow/Blue, Size: 2 in
My dog loves these. They are pretty sturdy. He’s a big chewer and they have held up. I put treats in the cracks to keep him busy when we are away. For some reason, his favorite is the blue! Good value.

Great for cats too!
Color: Blue/Green, Size: 2 in
Love it, perfect for my cats. Keeps them busy and slows down treat time. 4 stars only because they don’t seem very durable for hard core chewers, one of them already showing signs of wear.

Best play ball for small dog!
Color: Red/Yellow, Size: 2 in
Best play ball for a Jack Russel or any small dog that likes to play with a ball. The “teething like shape” give a good grip and my JR loves this ball.

Tough ball, but doesn’t fit treats through the center
Color: Blue/Green, Size: 2.75 in
Tough toy for chores dogs that chew, but it does not hold a Denti stick
Will probably buy the product by Woof I don’t like the fact that I have to buy their proprietary chews
