The rattlesnake vaccine (crotalus atrox toxoid, distributed by Red Rock Biologics) is a preventative for dogs that reduces morbidity and mortality due to intoxication with atrox toxoid toxin. In other words, it reduces the effects of snakebite (including pain and the chance of permanent injury) and makes your dog more likely to survive the bite. It is far less expensive than antivenom injections which can cost hundreds or even thousands of dollars. The vaccine is most effective against bites from the western diamondback rattlesnake, but also provides protection from other species, such as the western rattlesnake, sidewinder, copperhead, et al.How long does the vaccination last?
From Red Rock Biologics: “The first time your dog is vaccinated, we recommend an initial vaccine injection followed by a booster dose about one month later.” This injection should provide protection for 6-12 months. We recommend boostering every spring (prior to the start of rattlesnake season) thereafter.
Red Rock Biologics has an excellent FAQ available on their website.
