Rattlesnakes are venomous, not poisonous, which can easily be confused. Venomous animals inject venom when they bite, whereas poisonous animals contain toxic tissue when ingested.
Most rattlesnakes do not attack unless they feel threatened. The best way to prevent your dog from getting bitten by a rattlesnake is to avoid them. As much as possible, keep your dog on a leash and be assertive. If you heard a rattling noise, it is likely a rattlesnake is nearby, which means it's time to head a different way. As long as you keep a long distance away from the rattlesnake, your dog and you should be fine.
Rattlesnake Bites
If your dog gets bit by a rattlesnake, head straight to the vet as soon as possible. Be calm and walk or carry your dog to the car, remembering that most snake bites are not immediately fatal to dogs.
Do not:
Suck out the venom (this is a myth)
Apply ice to the site
Administer anti-inflammatory drugs
Apply a tourniquet
Cut the skin around the site
Once you arrive at the vet, they will likely administer pain control drugs and antivenin, which neutralizes the toxins in venom. Antivenin is expensive, so it's best to avoid a rattlesnake bite at all costs.
Rattlesnake Vaccine
There is some controversy about the rattlesnake vaccine and if it actually is effective. Dr. Folland has spent years working with rattlesnakes, and can tell you the vaccine does not work well. Not only is it expensive, but there is not enough evidence to prove it actually protects a dog from harm. It was also created for a certain species of rattlesnakes. Protection against other species is unknown.
Have a fun and safe summer this year! Remember, prevention is the best way to keep your dog from getting bitten.
