In Texas, puppies are supposed to get the 1st vaccine at 4 months and a booster 12 months later. Once both of these vaccines are given, either a 1 year or 3 year booster can be given. My daughter told me that the vet she works for (as a registered vet tech) only offers the 1 year option as a way to ensure that owners bring their dogs in every year. Otherwise, they might wait 3 years between vet visits.

Also, from what I understand, individual counties in TX can make exceptions to the state law based on the history of rabies outbreaks.
