Seaweed in dog food
Seaweed is a popular nutritional supplement in natural dog foods. Although there are a wide variety of edible seaweeds, kelp is the most common one used in dog food.
Seaweed is a good source of a huge range of minerals including calcium, iron, magnesium and many more. They are also rich in the rare mineral iodine which is necessary for healthy thyroid function (please note that too much iodine can be harmful so large amounts of seaweed should be avoided).
