Not for aggressive chewers
The balls were fun and squeaky for about a week. Then the ball began to spli in half. We have two English bulldogs and they bite down hard when retrieving these. They enjoyed the noise as well, but we had to toss them a few weeks after they arrived.

My Dog's Favorite!
Color: Multi-colored, Size: Small - 12 Pack
My little Chi loves them! She constantly loses them so this is my 2nd purchase The only issue is that they are too hard to squeak very well. Still her favorite.

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.
