It's best for mid-size dogs like Miniature Schnauzers, Silky Terriers, Cocker Spaniels and Poodles, etc. The Alfie Pet Slow Eating Dog Bowls unique revolutionary design is a result of deep thought and research. The design was borne out of the observation of dogs gobbling up their food every time as if they came right out of a famine. This vacuuming of food may result in a myriad of physical and behavioral problems including overeating, vomiting and coprophagy. The design in the center of the bowl has 3 apexes, which serve as an obstruction to deter your dog from making a clean sweep of the food. The same obstruction also makes it more difficult for dogs to get their muzzles near enough to the base of the bowl, and thus preventing them from inhaling their food.
