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.

Great Toy for Endless Fun!
The JW Pet Hol-ee Roller Small is such a fantastic toy! It’s lightweight, flexible, and perfect for my pup to carry around and chew on. I love the design it’s durable enough to hold up to play but still soft on their teeth. You can even stuff it with treats to keep them entertained longer, which makes it super versatile. The small size is just right for my little dog, and the assorted colors are a fun bonus. This has quickly become one of their favorite toys! Highly recommend for small dogs who love to play and chew.
