One way of making sure your dog gets his 5 a day..... Seaweed is a much overlooked source of all sorts of vitamins, minerals and other good nutrients.
I particularly like a nice bowl of Chinese hot and sour soup which
traditionally contains seaweed.
Sea weed is regularly used as a food source in China and Japan. I'm not sure why we don't make more use of it as it can be very tasty and we have so much of it available around our extensive coastline.
I add Mara seaweed at the table as well as salt.
