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.

    Koda loves this thing!

    This is bigger than expected (in a good way), and you can tell it will be long-lasting. We use this for treats, and also as a 'slow feeder' for our dog, Koda. It keeps her engaged for quite a while. The 'dispensing' holes are a good size for kibble and smaller treats and the larger/slotted 'fill' hole works well.

    Great enrichment toy

    My guys LOVE when they see their “rocks” come out. I put broken up treats inside and it keeps them occupied for at least 30 mins of play to push around the rocks!

    Glad I purchased.
