**ALL DOGS EXPOSED TO RATTLESNAKES NEED THIS VACCINE**
This vaccine decreases reactions to rattlesnake venom, and may save your dog in the event the bite is not witnessed. In the case of a known bite, it should still be treated as an emergency, as the protection can be overwhelmed by the amount or location of the venom, and snake bite wounds often become infected.
When first given, it is given twice, one month apart (3 times if the dog is under 25 pounds or over 100 pounds). It is boosted every spring, to be strong in our rattlesnake season. If your dog travels to the south, where rattlesnake season is all year, it should be boosted twice yearly.
