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

    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.

    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.
