🐍 Rattlesnake Alert: What You Need to Know to Protect Your Pets 🐾
As temperatures begin to fluctuate in Southern Arizona, rattlesnake activity increases — and so does the number of snake bites we treat in the ER. At our hospital, we’re already seeing a climb in patients affected by venomous bites, and we want pet owners to stay informed and prepared.
⛰️ Why Now?
Cool nights and warm days in late summer and early fall often drive snakes out to bask in the sun. This seasonal behavior means your curious dog or cat is more likely to encounter a rattlesnake during hikes, yard time, or even walks around the neighborhood.
🔬 When a Pet Is Bitten
Rattlesnake envenomation is a medical emergency. Beyond visible swelling and pain at the bite site, venom can cause serious systemic effects, including:
• Hemolysis (breakdown of red blood cells)
• Coagulopathy (inability to clot blood properly)
• Severe tissue damage and shock
• Organ dysfunction in advanced cases
🧪 What We Look for in the ER:
• Blood smears may show echinocytes (spiky red blood cells), a telltale sign of envenomation.
• We assess clotting times, platelet levels, and organ function through bloodwork.
• Monitoring for rapid changes in cardiovascular and neurological status is critical.
💉 Antivenin Treatment:
If envenomation is confirmed or highly suspected, antivenin transfusion is administered promptly. This life-saving therapy helps neutralize venom and prevent further systemic damage. Time is crucial — the sooner it’s given, the better the outcome.
🛑 What You Can Do:
• Keep pets leashed and out of tall brush or rocky areas during walks.
• Be vigilant during early mornings and late afternoons.
• If you suspect a bite, do not wait — seek emergency care immediately. Do not try to suck out venom or apply tourniquets.
We’re here 24/7 to treat rattlesnake bites and any other emergencies. Stay safe, and share this to help fellow pet owners stay informed this season!
