Not very durable
Color: Blue
Dog loved the toy but tore through it in less than 15 minutes. Sure didn’t last long.

A great toy for large dogs
Color: Blue
This toy has definitely gotten my dogs interest. I highly recommend it for people who have large dogs who are trying to keep them entertained. Well, worth the price!

Great for my Corgi
Color: Blue
My pup loves this toy! The soft casing is strong and durable, which prevents my pup from getting to the ball inside. It has a great battery life! Would definitely recommend for herding dogs.

Yes!

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

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.
