I took Wrigley to the vet today for his 9 weeks vaccinations. While I was there the vet tech casually mentioned to me that I shouldn't put Wrigley down on the floor at the vet office until he is fully vaccinated. I understand that this is probably so that he doesn't get exposed to anything too early, but then I wondered how early should I start socializing him with other dogs? In everything I've read they say the earlier the better, but am I exposing him to harm if he hasn't had all of his shots? What have all of you done?
