LARGE CAPACITY DOG SELF-FEEDER: Your dogs simply push down on the dispenser, and the base fills with fresh, dry kibble. This keeps food fresh, dry, and protected from pests and scavengers. With a generous 25-pound capacity, you'll spend less time refilling and more time enjoying your dog's joy of chowing down. SIMPLE MAGNETIC DOOR OPERATION: A magnet securely holds the dispenser door closed. Your dog can easily nose or paw the door down for self-feeding. Our feeders come with slots for wall-mounting, making it ideal for raising the feeder to a height that suits large and extra-large dogs.
