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.

Great interactive toy. Holes could be smaller.

Great toy to keep our 70lb shepherd occupied. We have a similar plastic ball treat dispenser from another vendor, but this one works way better on our tile floor. The plastic ball will just fly across the room and collide loudly with furniture/walls when our dog pushes it, but the Gnawt-a-Rock rolls much more controlled and is quieter. The holes are little bit too big, so we have to use larger sized treats/food so it won't dispense all at once. This means he eats more food per session and so unfortunately we can only play occasionally (unless he cheats his diet).

So Great!

Our short-haired pit mix actually likes the snow and rain with the help of his Ruffwear Jackets! Also, meal time is WAY more fun with the Gnawt a Rock. Super stimulating and a great way for the pooch to get out some extra energy.

Beats boredom

My dog loves this toy. He has a lot of toys. I mean a large basket full. The only ones he can't destroy are ruffwear. Due to the size and weight, this falls to the bottom of the basket, literally. He throws the rest out to dig this up. Then he rolls it around the house, pouncing on it, punching it, picking it up and dropping it. He loves it. I've also been using it for meal time. I load up the kibble and let him go to town. There have been a few "couch and fridge" situations (he drops the toy so hard the kibble scatters under these hard to reach areas), but avoiding disaster, this has kept him stimulated in the winter when exercise outside is harder. It's fun for me to watch him figure it out too. I will get all of the rubber ruffwear toys because I know they will last.

Keeps them busy for hours

This toy is great. Its also still intact after hours and hours of my dogs trying to rip it open. Not to mention it’s also entertaining for me to watch them chuck the ball across the room in effort to get the treats out.
