Do I really need to vaccinate against Leptospirosis (Lepto)?

Yes. Leptospirosis is a zoonotic disease (transmittable to humans) and has greatly increased in occurrence in recent years. We have seen several infected animals here at Oak Knoll, in fact.

Lepto is contracted through contact with wildlife or wildlife waste. Simply drinking from a stream in which raccoons have urinated may be enough to infect your dog. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
