Below is a link to an actual study trying to prove that the period between vaccinations could be lengthened. When each of the dogs was challenged with rabies virus 100% of the dogs died when challenged at various length intervals after 1st year vaccination. 20% at 5, 50% at 6 and 80% at 7 years. Besides all the legal reasons for vaccinating, leaving your dog vulnerable to what is an excruciatingly painful way to die it is a very selfish way to demonstrate your philosophic or religious aversion to vaccines. Only humans philosophize and therefore can, as they pass through the excruciating trials, find peace in knowing they lived true to themselves.
