There is a rattlesnake vaccination for dogs. It technically works better in cats but as of now it is not available through vets.
A decision to vaccinate your dog should balance the risk and consequence of a venomous snakebite with the risk and consequence of vaccination. We recommend that you talk with your veterinarian about these risks.
If your dog is bitten by a rattlesnake then get them to the vet ASAP as it is an emergency – even if they already had the vaccine. Six weeks after being bitten your vet may administer the rattlesnake vaccination.
Here are some tips from Cesar Millan on Avoiding Snakes:
- Keep your dog on a leash in areas where snakes may reside — woods, marshes, grasslands, and near bodies of water. While in these areas especially, it’s crucial to keep an eye on your dog at all times. Don’t allow her to dig through dirt or riffle through leaves where snakes may be hiding.
- When hiking and exploring outside, stick to paved trails where the visibility is better.
- Avoid hiking or walking through snake-infested areas at night. Many types of snakes, including varieties of rattlesnakes, tend to be more active once the sun has set.
- If your dog becomes startled by something, back away until you know what exactly he has encountered. If you hear a warning “hiss” or “rattling” sound, slowly retreat from the area as this could be a rattlesnake’s way of telling you to back off.
