Bounce it.

Inspired by the natural volcanic glass formed by rapidly cooling lava from Pacific Northwest volcanoes, the Gnawt-a-Rock is made with natural latex rubber, with a faceted, gum-massaging surface to help your dog have hours of fun. Its irregular shape creates an erratic bounce for your pup to play with, and it has a treat-dispensing design for interactive play and reward.

Best toy ever!

  • Familiarity: I've put it through the wringer

Hello, I'm Bruno and find this toy thrilling. It makes me incredible happy for some reason humans don't seem to comprehend. It bounces like crazy, humans kick it or toss it whenever they see it so is fun to chase. Fits in my mouth just fine so I carry it everywhere and shove it to humans to entice them to play - sometimes it doesn't work but I think it might be because of my unending stream of saliva on top of the toy. I have tried really hard to break this apart but I haven't figured out why it doesn't. Anyways, I'm hoping my human brings me more toys like this one.

Best toy ever!


  • Familiarity: I've used it several times

My dog spazzed out so hard when I gave her this toy (without treats inside) that I wondered if there was a canine equivalent of catnip and if Ruffwear was coating their toys in it. She seems pleased with the rock and will roll it around with her nose and periodically ambush it. Despite her best efforts to tear it apart it is holding up well. The rock is bigger than the picture makes it look. It's close to 4"x4"
