Whistle away my friend!
Size: 2 Count (Pack of 1), Style: Pack of 2
Love it! My dog loves it! The people at the dog park love it! The whistle is the best thing about these balls but the hard durable rubber and the denseness of the ball really make it fly. Let me quickly breakdown each of these: First the sound is like a...well, whistle coming from a human but oscillating and slightly different. It helps the dogs track where it goes and helps them find it better when it is getting dark (while flying of course, not when it is stationary). It barely makes a sound when throwing it with the wind but really howls when throwing it into the wind. This is why you get this ball and most everyone at the dog park perks up and wonders what that is, asks about it, and thinks it is very cool; which it is! Next is the durable rubber which doesn't have a single bite mark or split yet in 4 months of constant daily play for about 1 1/2 hours every day! The dog chews it as he brings it back and other dogs steal the ball and run with it while "killing" it perpetually and it has held up great. I don't claim this is going to be Kong ball durable but it is very well chosen rubber. Last is the denseness of the ball which really makes to go far in a chuckit launcher. One doesn't really notice how far this goes until going back to a tennis ball and realizing how short a tennis ball goes compared to this. The whistler ball, and presumably other chuckit rubber balls (glow, irregular bounce), go 30-40% farther when I throw then using the longest chuckit thrower. This is excellent and wears my retriever out even faster; not to mention the rippling muscles he has from sprinting that whole way! Overall I got both ball several months ago and we started with the blue ball and haven't had to touch the orange one yet. This is his goto ball at the park and it is the most popular ball, bar none, for all the dogs to steal. The bright blue aspect, the rubber aspect, the sound, and exclusivity of it make it coveted by dogs and owners. I might be gushing and glowing over this ball a bit much but I tend to do that when something unexpected ends up being part of your everyday life and blows you away at how wonderful it is.

Great for dogs that are chewers
Size: 2 Count (Pack of 1), Style: Pack of 2
These are wonderful for our dog. The bright colors help us find them when our dog can't. The size is perfect to play fetch. Our dog will chew on it a bit and it stays together and does not fall apart. That is a big bonus because our dog is a chewer!

It's A Whistler!
Size: Medium (Pack of 1), Style: Pack of 1
This Chuckit! Whistler Ball is basically a regular fetch toy that decided to become an annoying little teakettle mid-air. My dog goes absolutely nuts for it—every throw sounds like a tiny referee is shrieking "foul!" the whole way across the yard. He chases it harder than he chases the mailman, and bonus: I can actually find it in tall grass because it's screaming for help. Super bouncy, tough enough that he hasn't destroyed it yet (miracle), and now our walks sound like a low-budget horror movie.
