Here in Harris County, part of Houston, we have to vaccinate for rabies, and I would want to even if we didn't, simply because rabid bats and other critters are found every so often around town, adn since my dogs are very mouthy they are bound to pick something dead or halfa– dead up, if they had the chance.
We live in the outskirts of Houston, and we have lots of bats flying around in the dusk hours, I like that, keeps mosquito populations down..
So far they have not found any rabid bats in our area of town, but you never know when that might happen..
If you do the 1 yr vaccination , of course it is good for a year, but if you do your booster within that years timeframe it counts as a 3 year shot. My vet stated that the dosage/strength is the same for both shots, it is simply a matter of how much your dog has in his system...(?)
I don't like to vaccinate for tons of different reasons, one being because I truly believe it compromises the animals health over the long run, but for diseases like rabies, I wouldn't take a chance.
Otis did not have a reaction to his first shot..so I hope he won't when he gets his booster around march/april next year.
