Ruffwear's Gnawt-a-Rock is made of natural latex rubber and has a faceted, gum-massaging surface.  Play fetch or fill it with treats or xylitol-free peanut butter.

The Gnawt-a-Rock's irregular shape creates an erratic bounce that dog's will love.  Plus it has a treat-dispensing design to hold small training treats for interactive feeding, play & reward!

This is a large toy so suitable for large-mouthed dogs.

Diameter is 4.5" (11.5cm) and can hold up to 2 cups of kibble!

Please note: All Ruffwear toys are interactive and intended for supervised feeding & play.  They are not designed to be chew toys. Once the interactive play / licking for treats has finished, place the Ruffwear toy out of your dog's reach and replace with a designated chew toy.

Also: If any part of this toy becomes loose or detached, immediately take the toy away from the dog and discard the toy.

Better than a Kong

Keeps our intelligent GSP X entertained for longer than a Kong does. The various hole shapes and sizes and flexible material is great for getting all different kinds of treats in there. The material is kind on the hardwood floors when dropped, and the uneven shape makes its movement unpredictable. Great product!

Hours of Entertainment

My 7 month old Doberman puppy has lots of fun eating kibble from this dispenser. He can pick this up in his mouth easily. Unlike his other slow feeders this toy is made of rubber and when it hits the walls inside it isn’t noisy. Washes well in the dishwasher.

Super easy to pack with food. Very durable. Bounces quite well too! I have a 45kg GWP and it takes him about 20+ minutes for him to work at it constantly and he has such a good time.

This rocks! 🤩

With a Lab appetite our dog needs feeders that slow her down. She loves this, its fun, the large kibble dispenses well .. not too slow or fast and keeps her occupied for much longer than the slow feed bowl. Easy to fill + wash/dry in the dishwasher.

My 8m Labrador is a chewer and loves his food. This treat dispenser is large enough for a whole meal, keeps him entertained for ages, is soft so he can chew it but strong enough that it doesn’t seem to do much damage - and it’s not as loud and hard on our surfaces as some of the other popular equivalents. The uneven edges mean he can’t predict where it will bounce, so he stays engaged. Highly recommended


My dog has enjoyed this. It dispenses treats quite easily, just gotta find something a little bigger so he has to work harder!

Very happy pup since this arrived. Happily plays with this time and time again. It’s nice and quiet inside and easy to clean. Only thing is that it’s sometimes too easy for the treats to come out.
