Outward Hound uniquely designed Fun Feeder dog bowls feature meal-lengthening ridges to help slow down your dog's eating time by 10X! Common issues that arise in fast-eating dogs include bloating, regurgitation, and canine obesity. Our Fun Feeder Slo Bowls both challenge and engage your dog during mealtime while helping reduce overeating behaviour. Outward Hound's Fun Feeder Slo Bowl, slow feeder dog bowls are made to hold in both fun and food as your dog forages through the fun patterns with its non-slip base.

The Large/Regular holds up to 4 cups of dry kibble, the Medium/Mini holds 2 cups, and the Small/Tiny holds 3/4 cup. Fun Feeder dog bowls are top rack dishwasher safe. Less work for you means more pup playtime after!
