It looks like a piece of Obsidian from our nearby lava flows, but it’s Gnawt-a-Rock™! This durable throw toy is inspired by natural volcanic glass formed by rapidly cooling lava from Pacific Northwest volcanoes. Unlike Obsidian, the Gnawt-a-Rock is made with natural latex rubber, with a faceted, gum-massaging surface. Its irregular shape creates an erratic bounce, and it has a treat-dispensing design for interactive play and reward.
Part of the Pacific Gnaw-west toy collection inspired by Ruffwear’s home of Bend, Oregon, and its natural surroundings.
Diameter: 4.5 (in), 11.5 (cm), Holds up to 2 cups of kibble.
Please note: If any part of this toy becomes loose or detached, immediately take the toy away from the dog and discard the toy.
Internal chamber dispenses up to 2 cups of kibble or small training treats.
Made from natural rubber, a renewable, sustainable resource.
