JMO but I would follow your breeders advice because that is what I tell the people where I place my pups. My vet has told me awful stories and I prefer not to experience them. When I show a pup they have had at least 2 sets of shots and I require that they wash their hands with antibacterial gel soap. Parvo can stay in the ground for years so do your research and get some advice from you vet if your set on letting him outside.
