[Ellie May]

I agree that lepto is a very serious disease and the vaccine is usually said to be "not a good thing" too often. It can be a very dangerous vaccine and at this time I would most likely not give it to any Yorkie of mine but that is taking a big risk, especially in Michigan. Then again, a lepto single (like Pfizer's) may be a consideration. This doesn't go for Ellie because she can't have it. Pfizer has one now that isn't in a combo shot. In my opinion, giving it separately is the way to go if you HAVE to give it.

Some vets don't suspect lepto often enough and then it is low on their list of things to look for when an animal is sick, so the disease progresses.

This is really an individual decision and should be based on research and what the owner is comfortable with.

As long as it's caught early, the mortality rate is about 10% I think.

This is why some vets push the vaccine.
They aren't looking for money.
They honestly feel it is best and for good reason.
But I would not use the vaccine before about 16 weeks either.
