It's a Hit a Our House!
Size: Large
My strong chewer is still ..... Well, going strong! He loves his new crackle ball.
He enjoys the new sound, the bounce back feeling in his jaws when chews.
Mom is happy that pup hasn't put a dent in the toy yet!
Price was more than reasonable too.
We give it 5 Paws Up!

Medium size preferred.

I purchased both the large 4" and the medium 3" balls. My 80 lbs German shepherd much prefers the medium size. Show loves to play fetch with it and its lasted well!
