the vet called to tell us it was time for their next parvo shot but after the third visit we were told we didn't need anything else till they were a year. Are they just trying to get more money or is it really beneficial for the pups. they are 18 wks old. Do you believe they are over vaccinated?
It depends when the first one was done. If it was before 8 weeks some vets require a 4th because they consider that the first was done too early. I would think he was done tho if he is already 18 weeks.
