I don't know hardly anything about vaccinations (ah, the joy of having one's first and second dogs and the lack of knowledge that comes with it ). But both dogs have been fully vaccinated, as their vet said they needed to be. So, all puppy shots, done. So why then did I get a reminder in the mail to schedule Molly for a DA2PL vaccination? Isn't that one they give to puppies? Molly's only a year old, it can't be time to renew yet, can it?
