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.

    Congratulations on your new puppy. Deworming susually start at around 4-6 weeks of age and vaccines start at around 8 weeks so Coco is a little behind schedule and should get these done right away. I would recommend scheduling an appt with your local vet as soon as possible and to not expose Coco to any unvaccinated pets or to the outside until she is fully vaccinated. Best wishes!
