K9 Natural Food presents K9 Natural Air-Dried Protein Bites, an everyday treat packed with protein: lung, specifically, from 100% New Zealand grass-fed, free-range beef and lamb. Air-drying is a slow, low-temperature process. The low-temperature air slowly circulates and dries the meat, and at the end of the process, a higher temperature kills all the pathogens in its path—with minimum impact on vitamins, proteins, amino acids and enzymes. The treats are perfect for on-the-go or training. Dogs will enjoy the dense, jerkylike texture, while owners will enjoy a crumb-free pocket. The treats are free of artificial preservatives and flavors.
