That's a really great question!  Vitamins work internally, making the various systems of the body work better and more efficiently. They act as health insurance by keeping the immune system and organs in good repair.  The long term results are better health.  The effects that are often visible just weeks after starting are a more lustrous coat and, depending on the age of the dog,  more energy.  Think about how you feel when you are your healthiest - your mood is better, you are more engaged in what's going on around you, your brain seems to make connections more quickly.  The same is true for your pet.
