The Oregon State Veterinarian just posted current information on Leptospirosis cases seen in our state. This is an infection caused by a Leptospira bacterium. There is a vaccine to prevent this potentially life threatening infection. This vaccine could be considered a "core vaccine" for your dog, depending on the region where you live and travel. This map shows the counties in red where there are active Leptospirosis cases reported this month. Please give us a call if you would like to discuss if this vaccine (initial, followed by a booster 2-4 wks later, then annual boosters) is recommended for your dog.
