The short answer is no, but possibly in the future.
We've tested The Odin on dogs as small as 5 pounds and big as 60 pounds with great results. The Odin's current size allows smaller dogs to roll it but prevents bigger dogs from being able to swallow it. If we were to make a different size, we'd have to buy another mold and place another large order, meaning we'd have to raise $25,000 per size! We really believe that The Odin will be good for dogs of every size though, even if your dog is a big dog with small legs.
