We're committed fans of the puzzle bowl here at Your Whole Dog.
This is what Outward Hound has to say about their Fun Feeder puzzle bowls:
Why do dogs feel like eating has to be a race? We have no idea, but we solved the problem anyway.
Featuring meal-lengthening ridges and mazes, Fun Feeders™ keep pups engaged for up to 10x longer at chow time, which improves digestion while helping furry friends eat at a fun, healthy pace!
Available in 5 unique colours and designs, the Fun Feeder™ also features a slip-resistant base to prevent sliding and food spillage.
Fun Feeders™ are top-rack dishwasher safe, BPA, PVC & phthalate-free, and available in mini (2 cups) and large (4 cups) sizes.
