The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most. |

It is a light, pillowy citrus gelatin with nuts - in this case Filberts. And it is cut into tiny squares and then liberally coated with powdered sugar. And it is a tiny mouthful of heaven. Not too chewy, and very flavorful. I highly recommend this yummy treat. If you are familiar with the story of C.S. Lewis' ""The Lion, The Witch, and The Wardrobe"" - this is the treat that seduces Edmund into selling out his Brother and Sisters to the Witch." |
