Vaccines can start around 6-7 weeks of age and should be boosted every 4 weeks until 16 weeks of age. Discuss an appropriate vaccination protocol based on Snoopy's lifestyle and risk of exposure with your veterinarian. Snoopy should be kept away from public places and dogs of unknown vaccine status until about 2 weeks after his last round of vaccines. Deworming can start now and should be done every 2 weeks until 12 weeks of age. Transition to a monthly preventative afterwards. You can submit a stool sample to your veterinarian to confirm infection, identify the parasite or to confirm clearance.
