Some dogs are susceptible to certain ingredients in their food, causing for example stomach & intestinal disorders. Yarrah Multi Dog Biscuits are composed in such a manner that the chances of allergic reactions & digestive problems are virtually negligible. The Yarrah Natural Biotics® Health Program has identified Seaweed & Spirulina as a natural substance that can have a positive health effect for your dog. Although the health benefits of Seaweed & Spirulina have not been medically proven in dogs (Yarrah will not test on animals), the general consensus is that Seaweed & Spirulina can improve coat condition & vitality.
