Could you please summarize your routine vaccination recommendations for puppies and then older dogs? Do your suggestions change by region? I live in the Pacific Northwest, where there have been rabid bats but there appears to be little distemper/parvo. On the other hand, I lived for a while in Costa Rica and saw a whole village of dogs wiped out by distemper/parvo. Do you have a link to the "best practices" for USA? Thanks!
