Chuckit! The Whistler Ball Dog Toy, Color Varies

Immediately this ball became our Airedale's favorite toy and ball. As in other reviews, there is a bit of mystery with this ball. If you are expecting a loud whistler noise, you are in for a surprise. You can just barely hear it, but the dog dearly loves it. Someone said kind of like a dog whistle?? Something for sure ?? It is also tough and she has tried to destroy it, a power chewer, but has been unable after a month. Strongly recommend for at least Airedales??

My dog LOVES these. She prefers them over the Ultra. If I'm throwing an Ultra and a Whistler, she goes for the Whistler. And she won't even touch the Breath Right balls, but these serve the same purpose due to the holes. Also, she's infatuated with the blue Whistler. Can't understand why. But blue is my favorite color too.

Awesome product. 60 lbs Chewer can't destroy it. He loves it. Great fetch ball but also doubles as durable chew toy. whistle aspect of ball is sorta a fail. and the saliva, grass, and debris now gets trapped in the hole so cleaning it takes more time than regular Chuckit ball.

My dog goes through tennis balls every 5 days, but this one seems to hold up. When he plays fetch he has a tendency to chew the ball in between throws, but this one doesn’t break down like the tennis balls.

My boy literally won’t play with any other type of Chuckit boy when we play fetch. I bought this in a variety pack and have tried each one, he refuses to fetch if it’s not this ball! Purchasing more in case we lose the one he has now!

The ball is great don't get me wrong, I mean my dog loves all the bouncy chuck it balls. None the less it doesn't make any whistling noise. When I first bought it I hear air pass through it that's about it.

It makes the strangest sound but my dog seems to think its the best sound on earth. He gets way more excited to get the whistler than a normal ball and then he gets the zoomies when he brings it back. Its a nice durable rubber but I dont let my dog have it for normal chew/play time, just outside for fetch so cant say much about the chewability. Its the same size as a standard tennis ball

My 55 pound pup loves these whistler balls. They are sturdy and make a soft whirring noise when flying through the air. The dog likes to chew on the ball (as if she's chewing gum) and the ball is still whole.... i love this!

My dogs love this ball. It was sort of disappointing though because it didn't make a whistling sound when you throw it. It doesn't seem to matter how hard you throw it. They still like it anyway.

Disappointed that these balls do not whistle when thrown. I would not have purchased them had I read that you have to buy the launcher to get the whistle sound. The balls themselves are O.K. and my dog plays with them.
