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)
