The reason I ask is because it's important to know how old the puppy was when the vaccination were started. The reason why we give multiple sets is to ensure that we achieve immunity. For the first couple of weeks of life, a puppy gains it's immunity from the mother. A puppy just weaned from it's mother will still have those maternal antibodies which means vaccines don't work because the antibodies essentially neutralize them. If your puppy has had 3 sets since 8 weeks, I'd say your covered. If they were started at 6 weeks, it might be a good idea to ask your vet again. |
