Can dogs eat Hijiki seaweed (boiled)?
Hijiki seaweed (boiled)（ひじき（ゆで））
Safe to feed
A seaweed with fiber. Iodine is on the high side.
11 kcal per 100 g
What kind of food is this?
A type of seaweed. Light at 11kcal per 100g, with 3.7g fiber, on the high side among the seafood we list.
Iodine is 960µg per 100g. Its appeal is fiber you cannot get from fish flesh, delivered by a sea vegetable. With that much iodine, though, for dogs under thyroid treatment or care it is something to discuss with your vet.
How to serve
When preparing from dried hijiki, soak it in water and discard the soaking water, then boil it and discard the cooking water as well. The trace amounts of inorganic arsenic in hijiki dissolve in water, and research by Japan's Ministry of Agriculture, Forestry and Fisheries has shown this preparation greatly reduces it.
Seaweed and iodine
Seaweed is rich in iodine, but the amount varies greatly by type.
Stacking several kinds of seaweed on the same day makes it easy for iodine alone to add up. What matters is not just the amount of each one, but how much seaweed you are using overall.

In food-energetics terms
In food therapy, this is classified as 'cold.' It is said to have a strong cooling effect and is often chosen in hot seasons. For dogs prone to feeling chilly, keeping it modest is safest.
(Food energetics is a long-standing idea of supporting the body through everyday meals. Treat it as one extra hint alongside the nutrition numbers.)
