Strengthening younger animals’ immune systems with antioxidant supplementation may prevent illnesses, delay age-related diseases, and promote better responses to traditional therapy if illness does occur. Furthermore, studies have shown that puppies whose diets have been supplemented with antioxidants have a stronger immune response to vaccinations. Veterinarians often include ProAnimal in client puppy kits. Puppies coming from kennels or shelters often have compromised immune systems, and supplementing their food with ProAnimal strengthens the immune response.
