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.

Chew Style: Power

Play Style: Fetch & Puzzle

Size: 4.5 in (11.5 cm) Diameter

Our toys are designed to be interactive – it's just more fun that way. While our toys suit a range of play styles, dogs can be crafty and determined chewers, so supervised play is recommended. If any part of the toy becomes loose or detached, take the toy away and discard.

    Robust and well designed

    Overall, a well designed and well manufactured dog toy. My dog finds it just the right balance of interesting/challenging and the material seems to stand up well to rough play and the occasional nibble by my pibble.

    No complaints.

    I have a canine vacuum cleaner

    My Smooth Collie , Bohdisattva, eats Anything, and does so at incredible speed.

    This :slows him down, delights him, somehow stands up to razor sharp tools.

    I'm most likely going to order another.

    He loves it!

    My boy loves his new treat dispenser toy!! He bats it around with his paws and rolls it with his nose. Figured it out pretty quickly, but loves to see it come out again every time. Sure am glad I found out about it and found it online and bought it. Thanks!!

    My dog loves the texture and chewiness of the gnaw-a-rock. She likes getting treats from the toy. Great item!
