Puppies should have their initial examination around 6-8 weeks and kittens around 9 weeks of age if there are no signs of any problems or concerns. Multiple immunizations at different visits will be required to get your new pet’s immune system ready for exposure to the environment outside your home. Puppies and kittens are highly susceptible to viruses, infections, and/or parasites and proper early care and screening help to give your new baby the best start in life.
