Great to throw 3” KONG Ball (RED) with hole thru it! The thrower is the best to exercise dogs with retrieving balls!

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!

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. 😁
