makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.

Blue ball, my dog likes blue.

Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼‍♀️

One of the best dog toys I’ve found

Color: Blue, Color: Blue

My Great Dane puppy- at 140lbs, loves this!! We had another one that was plastic and it worked ok but this is so much better! Interactive, soft to play with, battery last a long time & he does not get bored with it. Besides is plush lamb chops, best toy ever bought for him.
