Great chew toy
My dogs love this toy and we still have it a month later. That’s impressive since they are aggressive chewers.

Not as durable as they would want you to believe.
This was an easy demolish for my aggressive chewer!! Got this for my Rudy for Christmas!! Didn’t last long.

Great buy
My dogs absolute favorite! Super durable and keeps him busy forever. The squeaker is fun but it’s nice because it’s not an easy squeak so the annoying part of it is actually tolerable. The size was perfect for my 100+lb German Shepard. I’d buy 100 more once he dominates this one.

Defiantly works for aggressive chewers!
This is awesome! My husband just knew our dozer would tear it up into pieces and he hasn't . It has lasted so far with our aggressive chewer! Will buy it again!

My Dog Approves of this Toy for Agressive Chewers
My dog is a mix of a Husky and a Pit Bull. She needs to chew toys, but they usually don't last long. This one seems to be an exception. She took to it right away, and it's still in one piece pi. I assume that the bacon flavor or scent is what keeps her coming back to this toy. This one seems to be her favorite so far.
