Hello. A puppy should be examined for general health & the presence of intestinal parasites by your veterinarian now. It is never a good idea to just deworm because you may be missing some important parasites like coccidia. Vaccinations are usually started at 8 weeks of age & boostered at 12 & 16 weeks of age. Good luck with your new buddy.
