At nine weeks of age the distemper combination vaccination series can be started (sometimes called a 5-way, sometimes called a DHPP or DAPP. This vaccine needs to be repeated every 3 to 4 weeks until your puppy is 16 weeks of age. I would recommend an examination by a veterinarian if your puppy hasn't had one yet and getting his vaccinations done by a veterinarian. There are a few reasons for this. The vet can examine your puppy to be sure there aren't any health problems/congenital disease that are a concern. The vet can do a fecal test to be sure your pup doesn't have intestinal parasites, which are very common at this age. The vet can also discuss other vaccines that may be appropriate for your puppy (such as the bordetella or kennel cough vaccine and the leptosporosis vaccine). You can be certain the vaccines given by the vet are gauranteed to be safe and effective (and purchased by a company that gaurantees their efficacy and will pay for treatment if there was vaccine failure).
