not saying the vet did anything wrong (don't know), could have been any number of reasons the dog caught the parvo after being shotted. but included in that number of reasons are vaccine mishandling by vet staff.
before i started buying my vacs i asked the local houndsmen whon they buy from and while they all bought from different people they ALL told me who NOT to buy from and it was because there were eyewitness accounts of mishandling and people that had lost several dogs (one guy even lost his whole pack) because of it. a little investigating (really just a phone call out of curiousity) & i found the business in question had stopped carrying vacs because they weren't selling.
