When I was at the vets on Saturday, we were discussing vaccinations for Tatiana. I have never given my yorkies the Lepto vaccine.

Our vet was saying that there has been 2 cases of it in the area. He is now recommending it for adult dogs to get beginining at 1 yr and older. He isn't recommending it for puppies. What is Lepto? Should I worry about it with my pups? He said there is a new version of it and it is safer for yorkies. Anyone know about this?
