the shots from tractor supply are garbage. I know alot of people that have got screwed by there shots. There was a study done on how some tractor supply shipments of parvo shots didnt stay inside the temp. ranges that they were suppose to so that meant that the shots did not do anything for preventing parvo. Look into ordering online at dr foster and smith. If you buy in bulk its even cheaper than tractor supply for the really good stuff. Get vanguard plus. here is a link
