Rattlesnake Vaccine

Why is the vaccine no longer available?

The manufacturer of the canine rattlesnake vaccine has lost USDA licensing for distribution. As of now, the vaccine is no longer available for veterinary clinics to order or administer. Efforts are reportedly underway to renew licensing, but there is no confirmed timeline for its return.

Is the vaccine effective?

Recent studies have shown no statistically significant difference in morbidity or mortality between vaccinated and unvaccinated dogs treated for rattlesnake bites. These findings suggest that, particularly in moderate to severe cases requiring antivenin, prior vaccination may not offer significant protection.

What can I do to protect my dog?

Without access to the vaccine, prevention becomes key. We recommend the following:

• Keep dogs leashed and on trails during hikes
• Avoid tall grass and rocky outcrops where snakes may hide
• Consider snake avoidance training for high-risk pets
• Know the location of your nearest emergency veterinary clinic

What if my pet is bitten by a rattlesnake?

Seek immediate veterinary care. The most effective treatment for snakebites is antivenin, supportive care, and pain management. Time is critical — the sooner treatment begins, the better the outcome.
