Sea Kelp, Eggshell, & Oyster Powder Trio

A trio of natural powders to add iodine, calcium, zinc and other trace minerals to your dog's food. Sea Kelp (Ascophyllum Nodosum) is a natural source of iodine. Sourced from Canada. Eggshell is a natural source of calcium. Sourced from the USA. Oysters are the world's highest natural source of zinc. No other food comes close! Sourced directly from the Pacific Northwest in the USA. Gently cooked and freeze-dried to maintain nutrients and flavor. These natural powders are for use in homemade food. We don't recommend adding them to already balanced or commercial dog food. Check out our cookbook, The Dog's Table, for recipes!
