What It Does
Powers over 200 enzymes in your pet's body, affecting immune function, skin health, wound healing, and thyroid regulation. Zinc deficiency is one of the most visible nutritional problems in dogs — it creates distinctive crusty lesions around the eyes, mouth, and ears.

Sources & Notes
Siberian Huskies and Alaskan Malamutes have a hereditary reduced ability to absorb zinc — they often need lifelong supplementation. High-calcium diets also block zinc absorption in all breeds.
