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 🤷🏼‍♀️

Perfect for my dog!

Style: Flying Glow Squirrel

My dog loves it! It hovers in flight, making it easy to catch, and it’s easy for her to pick up since it’s not flat like a regular disc. It even went thru the washing machine without damage, but I let it air dry so the dryer wouldn’t tear it up. Will buy again!
