Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing.
He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.
