While your furry friend no longer needs to fight for food, those survival instincts can still persist even with the best trained pup. That's why at Outward Hound we've created the Fun Feeder Slo Bowl dog bowls featuring meal-lengthening ridges and multiple challenging mazes. Fun Feeder Slo Bowls keep pups engaged for up to 10x longer during mealtimes, which helps improve overall digestion while helping furry friends adapt to a healthier pace! With over 1 million these dog bowls sold, in multiple sizes and maze styles, you're sure to find one that fits your pup's personality and diet preferences. 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.
