Absolutely love WestPaw's Tux! It's super durable and among only 3 toys whose durability I trust enough to leave with my pack, even the more destructive pups. Large Tux holds about 1/3 of a cup of food, more if you load it up and freeze. The design is perfect as the dogs can hold it with their paws while figuring the puzzle out. I'm definitely glad I got the large as it's a firm favourite for refilling and distributing often.
