Diseases, worm infestation, vaccinations, stress and the risk of infection during winter weaken the immune system. In winter your dog might eat polluted snow and run happily through the puddles and mud. You cannot stop your dog, but you can strengthen his immune system. Help your dog to help himself to strengthen his defenses! This also applies especially for your puppy: New to the world, the little dog´s body has to deal with thousands of factors that affect him. From his mother he has got the "antibody protection" for some time, even breast milk strengthens him - but only partly. Support your puppies and help them to be able to overcome the first challenges in life!
