Puppies have a lot going on during the first 12 months of their lives. They are growing both physically and mentally, their immune system is developing, and they are learning about the world around them. Its a stressful time in a puppies life and we humans add to this stress by giving them vaccinations, medications, topical treatments and commercial food. There is so much we can do to help puppies get off to the right start in life. There are also so many things we should not do to ensure our puppies move into adulthood with a strong body and mind. We need to consider all aspects of exposure both internal and external.
