I've worked at veterinary clinics for many years, and have seen too many pups die to easily prevented diseases-- some because their "holistic" breeder told the new owners that vaccines were bad. Vaccinate your puppies-- seriously. :/ Their immune systems are NOT capable of warding off diseases like parvo unless they are vaccinated, and if your dog ever so much as sets a paw outside your house, they are at risk of being exposed to things that could kill them. The vaccination protocol currently recommended by most vets-- vacs as pups up until past 14 weeks of age and then boosters to DHPP and Rabies every three years until a satisfactory titer is reached-- is designed to minimize the risks associated with frequent vaccinations while still keeping the dog protected from disease.

Beyond that, there is a public health concern associated with unvaccinated dogs. If your dog hasn't been vaccinated and it bites someone, depending on the state that you are in, you might be forced to have your dog euthanized immediately without any recourse.

Titers are simple tests that monitor the level of antibodies in your dog's blood. They can be used to determine if a dog has enough antibodies to protect them from a disease, and then your vet can avoid vaccinating for things that your dog is already well protected from.
