Air Dried Duck Gizzards are prepared in Singapore using raw human grade duck gizzards from Malaysia. This is a single ingredient treat with no preservatives or flavoring added. The gizzard is a muscular organ used by the duck to grind up food because duck have no teeth to help them soften their food. Did you know that ducks will swallow small pebbles and keep them in the gizzard to help in the grinding up of their food? But do not worry, the gizzards that your dog get will be without stones as the gizzards are cut open and drained of stones before we air dry them. Air Dried Duck Gizzards have a great texture for your dog to enjoy as the muscle meat is tough and chewy. They also have an attractive aroma so it is hooman friendly. We hope this treat will give our duck loving dog customers more options in their treats selection! If your dog haven’t tried duck before we have Air Dried Duck Breast Crisps, Air Dried Duck Wings, Air Dried Duck Necks & Air Dried Duck Heads as well. Each packet contains approximately 100g of duck gizzards. Gizzards are in half palm size portions and suitable for dogs of all sizes.
