Seaweed is not a miracle cure for any disease, but it can be a valuable addition to your dog's diet. Various types of seaweed help boost your dog's health and immune system. Kelp and spirulina are the two most popular.
Kelp contains more than 60 minerals, 21 amino acids and several essential plant hormones. It's also rich in iodine. Studies show that kelp can make your dog's skin and coat healthier, increase his activity level, reduce allergy symptoms and help control a healthy weight level.
Spirulina is considered a great source of protein, as it is made of about 60 percent vegetable protein. It contains beta carotene, vitamin B-12, iron and various minerals that can strengthen your dog's immune system, improve gastrointestinal health, reduce the rate of cancer and help reduce allergy symptoms.
