Yes, I know not everyone is on board the snake vaccine.
And I don't put my dogs in places, just because I use it, and have them go through snake avoidance.
The fact is I live in Texas, and we have snakes. I can be proactive as possible. Or do nothing, and hope for the best.
I would rather be proactive.
I know people who have lost dogs to rattlesnake bites. Those same people now use the vaccine, and had a dogs recover after a rattlesnake bite. While it's possible the vaccinated dog, may have recovered without the vaccine. It still leads me to keep my dogs vaccinations up to date.
