Rattlesnake Vaccine Reports

The rattlesnake vaccine for bird dogs (or other working dogs whose habits put them at risk for snakebite) has been very popular. While the number of vaccinated dogs that have subsequently been snakebit are few, early voting by owners and DVMs have been quite positive. I had my Setters vaccinated recently as a peventive measure. If you have vaccinated dogs that become test subjects, I'd appeciate your evaluation of the encounter.
