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.
