Indestructable toy
Size: Medium/Large, Product Packaging: Standard Packaging
My dogs loves it and cannot tear it up no matter how hard she tries and squeaker is secure and excites her when she manages to crush the center ball. Loves to chase it.

Not Boerboel proof
I have a terrible time finding toys for my 10 month old Boerboel. Either she ignores it or tears it up immediately.
She likes this toy (jumbo size) and actually chewed on it for 20 min. Bad side is she chewed a hole.
It lasted longer than any of the other fairly chewy toys I've tried. She doesn't like the hard chews.

Favorite Toy
Size: Medium/Large, Product Packaging: Standard Packaging
My dog is a 3.5 yr old mix and this toy has been her favorite toy by far for three years. She likes it as a squeak toy, loves it as a tug toy and can't live without it as fetch toy. I roll it on its edge outside and she chases it - sometimes it take cool bounces or swerves and sometimes its just rolls straight and fast and whatever it does she can't get enough of it. She demands we play fetch with it at least three times a day. She's not a great releaser of fetch toys so there's plenty of tugging play involved too. We've had three of these over three years, but she's 75 pounds of muscle and it gets a work out every day so it's a really tough toy. All dogs are different, so I don't know what your dog will think, but it's been a fantastic toy for our girl.

So Bad
Size: Medium/Large, Product Packaging: Standard Packaging, Size: Medium/Large, Product Packaging: Standard Packaging
Had high hopes for this toy as Kong is fantastic with aggressive chewers as or Lulu is. This toy didn't last 30 minutes before she was able to tear it apart. The rubber and plastic are not of the same quality on nearly all there other toys she has. Have found better toys for half the cost. Kong needs to do better.
