My Boston's and Rotti love this ball. I had to get two more. It's great for the Boston's because they can grasp it with the way it's made with the softer rubber. They love the crackle sound. It's just the right size and weight for smaller like the Boston Terrier and Rotti. Easy cleaning, rinses right off.

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.

Size: Large

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!
