One problem with the lepto shot is that there a number of different strains of the virus and the shot does not cover all of them. I did recently read about a dog that died from lepto that had been vaccinated but the dog died from a strain that was not in the vaccination. I suppose if I let my dogs run outside I would consider the vaccination but since mine are strictly house dogs I choose not to give the vaccination. I worry about the long term side effects of the vaccination. |
