Best Iodine-Rich Foods for Dogs

Ranked by iodine content among foods safe for dogs in the Creature Feast catalog.

Salmon per 100g cooked: ~25–40mcg iodine Salmon is one of the best dietary iodine sources for dogs, delivering it alongside omega-3s and vitamin D.

Canned Sardines per 100g: ~15–30mcg iodine Canned sardines provide iodine from their marine environment alongside calcium from soft bones and omega-3 fatty acids.

Tuna per 100g canned: ~15–20mcg iodine Tuna delivers iodine from its marine diet. Use canned light tuna in water for a convenient, shelf-stable source.

Eggs 1 large egg: ~12–20mcg iodine Eggs provide modest iodine that varies with the hen's diet. Iodine-enriched eggs from supplemented hens provide more.

Nori sheets 1 small sheet (~2.5g): ~15–40mcg iodine Nori (seaweed sheets) are extremely iodine-rich and can be crumbled over food in tiny amounts. Use sparingly — seaweed concentrates iodine intensely.
