Although kelp cannot be eaten directly, there is no problem in making it into seaweed powder. First buy dried kelp, wash it, then use a pressure cooker to soften it, and dry it in the sun or oven. It should be noted that the large amount of salt in kelp is not good for dogs, and it takes a long time to clean. It is best to boil it in water, filter out the salt, and then dry it in the microwave. Then mash the kelp and seaweed, put them together with 20 golden vitamins into a blender and stir them into powder, mix them with the fish meal, stir evenly and put them into a jar, seal them well to prevent them from getting wet.
