Great Quality and durability

I have a teething puppy and this is the only ball that has outlasted the rest!! Big chewer and still bounces and no tears! Keeps him entertained for hours!! Sturdy, solid, good quality and value!

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!

Another great product from Chuckit!
Color: Ultra, Size: XL
Exactly the high quality that I've come to expect from Chuckit! The plastic/rubber used in their products is extremely tough yet gives enough that it's hard to actually pierce the it and tear apart. We have had Chuckit! Sticks and Balls with launcher for years and love them all. This particular ball is pretty big so my 45 pound pit mix struggles to pick it up but that's part of the fun for him. My 85 pound pit mix can pick it up no problem. The only "complaint" is that the two of them have been having so much fun with their new ball, they have already knocked something over and broke it.

Perfect for my mid size pit bull
Color: Ultra, Size: XL
Updating my review, the ball only lasted 5 days. I left the 5 stars because we had enough fun those 5 days to be worth the small price. She has dog has a lot of jaw strength, so I’m not surprised
We have a mid size foster pit bull. This ball is her favorite toy. It’s durable and the perfect size for her to play ball safely.

Good quality
Color: Ultra, Size: Large, Color: Ultra, Size: Large
Great quality. I purchased for my daughter’s dog who destroys all toys. This toy holds up. I didn’t realize it was a large and the chickit stick she had was a medium. The large ball ended up working out good for playing inside the house. The dog likes it a lot.
