Gus got the lepto vaccine at 7 months of age, and 7 pounds. I mention age and weight, because I think you should make sure your Yorkie is "hardy" before getting the vaccine if needed.
I didn't realize he had been given the vaccine until the vet suspected that he might have lepto, and ordered a blood test for lepto. Results came back positive for the lepto stains in the virus, positive for one other strain, and negative for the other strains. However, the positives were considered normal for vaccinated dogs. |
