I would hope the vets are testing to see exactly what strain of lepto is causing this. According to my vet, the lepto shot only works against 1 or 2 strains of lepto and there are at least 6 active strains out there (kind-of like the human flu vaccine).
I know it is a topic for much debate, but the fact still remains that all toy breed dogs are at an extremely high risk of adverse reactions from this particular vaccination as well......
