I just received notification from my vet's office that my dog, Buster needs boosters of Corona and Parvo Virus vaccinations. Mind you he received all these shots in February. Is this a new thing with vets to try and get more money out of the owners? I have always had my dogs vaccinated once a year, why are they trying to give them boosters now? I did call and they said that it wasn't necessary and I could wait until next year so it's kind of suspicious. Another thing is that some of my friends have been told that rabbies shots last 3 years and my vet says every year. What is up with all of this? Personally I think it is a scam to get us to pay. I don't see any of this as necessary and think that it is all a way of the manufacturers of vaccines as well as vets profiting from us and I even wonder if too many vaccines are bad for the dogs.
