Vetco Vaccination Clinic

Two pups, 7 and 9, went in for their 3 year Dapp2 vaccine. I get home and they gave them 1 year. They were due june 14th, this was june 19. I had taken them in may, they said too soon, thus time only appt 5 days after was available. Typically ok if within 30 days but not this vet. I was not consulted or discussed at appointment of change and when I called I was told I needed to show vet the records, although it was shown at check in. Looking like a way to get more money in a year, and an unnecessary extra shot.
