This is a Big Dog Boost Natural Immune Booster Supplement for Dogs (300 Gram). Understand that nutrition is the foundation of health and that a healthy diet is the key to this. However, there are situations where dogs need more than just a healthy diet. Very active, working and competing dogs, as well as older pets or pets with specific health challenges may require a little extra help. For this reason, Big Dog has a range of supplements to help keep our extra-needs pets in tip top shape. Boost contains potent immune stimulating, health promoting ingredients available to assist in correcting nutritional imbalances that may be present in your pet. Boost includes a broad range of easily digestible, natural amino acids, vitamins, minerals, enzymes, antioxidants and phytonutrients. Boost is formulated to stimulate the immune systems of pets recovering from surgery, illness, injury or trauma as well as supporting animals suffering from allergies, viruses, anxiety and other sensitivities.
