I have been doing a lot of research lately on the over-vaccination of our pets controversy. I found this article one of the most complete and concise that I have found so I wanted to share it with the members here as the question seems to come up frequently.
This vet gives her recommendations at the end, but I would suggest reading the entire article even though it is rather long. It is so important to your dogs' health.
