The Only Thing He Hasn't TOTALLY Destroyed
Size: Large, Color: Ball-Blue
I've spent my hard earned money on SOOOO many "indestructible " toys. This one is actually pretty good. It has a duck sound inside for when the pet rolls the ball to get the treats. I didn't use it for the treats. I gave this toy 4-stars because my dog broke the sound box while chewing it. We pulled the pieces out and he LOVES it. Great for play,and comfort. Sometimes, he sleeps with it. I guess you could say it's his favorite 😍.

Great for chewers!
Size: Large, Color: Ball-Blue
We have a super high energy one year old pup who destroys practically every toy she gets. This one is excellent! It makes a fun but not annoying sound and she hasn’t been able to destroy it yet. The test hole is a fun addition to keep her busy.
