Make sure you buy one for every dog in the house. I only purchased two, and I have four dogs. I did not think my older dogs would be interested in this toy. They never seem too interested in puzzle toys, but I forgot how food motivated they are. The dog I purchased this for didn't get to play with it! My older dog took to it right away and was rolling it all over the living room, while my bully breed grabbed the second one and guarded it, nudging it between his paws.
Endless entertainment! And that's what's important, because my Loki IS a goddess of Mischief! She can chew / destroy anything and everything, but has not succeeded in chewing this! Very well made. Great idea. Highly recommend.
