Truly Indestructible
Color: Blue, Color: Blue
This Is the first "indestructible" dog toy that really lives up to the claim. My dog is a power chewing destroyer of all things that squeak but after 1 month there's still not one piece of ball missing and it's still squeaking!! It is his prized possession. I've told all of my dog agility friends about it. Well worth the price.

Great ball, stands up to large breed chewers. We have had it a month now, and it still looks like the day we purchased and still squeaks. Great for playing fetch.
