The perfect ball for a small to medium dog.
Style: Ultra, Size: Small (2 Pack)
My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball.
A great entertainment value. This ball does not squeak.

Great ball!
Color: Ultra, Size: Large
Our puppy loves this ball. It has held up well so far, it’s about 2 weeks now of large breed pup play. It’s been outside for the last week, rain or shine, still in working order. Not as big as I thought it would be though. No squeak, bounces well. Thick rubber like material, that can be depressed when biting down.

Durable, even for a Great Dane!
Color: Ultra, Size: XXL
I've bought many tennis ball sized ChuckIt balls in the past (for medium sized dogs we've owned), so when we knew we were going to be babysitting our daughter's Great Dane, I bought a bigger one for her. The 4" is perfect for her! She plays catch with it, but also likes to gnaw on it. It holds up great!
