The Gnawt-a-Rock™ is a durable toy inspired by natural volcanic obsidian formed by rapidly cooling lava from Pacific Northwest volcanoes. 

Made with natural latex rubber and a faceted surface with an irregular shape, this interactive toy keeps your dog engaged, whether chasing after its erratic bounce or nosing it around as an interactive slow feeder puzzle toy to stimulate their mind.

Check out the Gnawt-a-Stick™ and Gnawt-a-Cone™ in our Gnawt-a-Toys Collection inspired by the natural surroundings in Ruffwear’s home of Bend, Oregon.

Size: 4.5 in (11.5 cm) Diameter

Reviews Summary
Customers say this treat-dispensing toy keeps their dogs engaged and entertained. Many reviews mention its durability and ability to withstand heavy chewing. The irregular shape creates unpredictable bounces during play, while the openings work well for dispensing kibble and treats. Some note the holes are slightly large for small treats, but most appreciate how it slows down feeding time. Reviews highlight its versatility as both an enrichment tool and play toy. The size works especially well for medium to large breeds, though some smaller dogs enjoy it too. Users particularly value its quiet operation on floors and easy cleaning.

    My dog is obsessed.

    From the second I removed the Gnawt-a-Rock from the package, my dog Birdie took it and trotted off to chew and lick it all evening, I didn’t even add any treats or spreads to it. She’s a large mix breed that is a heavy chewer and it’s holding up to her powerful jaws and she gleefully chases it to play fetch. All in all a win.

    Best slow-feeder ever!

    Our dog absolutely loves this toy! It’s also very quiet and kind to our wooden floor.

    Large dog owners rejoice!

    I have a Great Pyrenees and English Shepherd mix (aka a big farm dog) this is the ONLY toy that’s ever held up to her chewing and keeps her entertained for more than 10 minutes! We got one previously and it lasted 3 YEARS!!!! Safe to say that Ruffwear. . . Please never stop making these ❤️

    Great toy!

    It's holding up well so far to chewing though my pup is learning fast it's more about the food than chewing it. It rolls irregularly which makes it more interesting for my pup, and I think it'll fit a wide range of kibble as well as smaller treats. We pop training treats in it so we can use quite a few. Overall great toy / puzzle!
