Value for your money
Style: EcoFetch
It's definitely different from the one I lost. It's taking me some time how to throw the ball correctly. It's a hit and miss but we are getting there. When I do get a good throw, it really wings it out there.

Yes!

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

Balls
Size: Medium
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.
