It looks like a piece of Obsidian from 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.
