yeah
i have never ran in to a problem with lepto..i gave it to my yorkie poms when they were 6 weeks..and every vet that i have ever taking my dogs to gives lepto..they actually look at me funny when i ask them about not givng lepto..
and trust me i have been to at least 6 vets in my area and they all say its fine...but i believe this theory If YOU arent comfortable with it, then dont give it.
