Rattlesnake bite on a dog
Assume urgency. Calm carry, call ahead, and drive — antivenom decisions are clinical.

| Scenario | Snakebite |
|---|---|
| Vet vs poison control vs ER | Snakebite is an ER case. Call ahead so the clinic can check antivenom availability. Poison control may help with snake ID in some regions but does not replace emergency care. |
Immediate action steps
- Move people and pet away from the snake
- Limit the dog’s activity; carry if possible
- Do not cut, suck, ice, or tourniquet
- Call the ER about antivenom availability
- Transport promptly
Regional reality
If you live where rattlesnakes are common, save the ER number in your Emergency Passport before season starts.
Vaccine conversations are preventive planning with your vet — not field treatment after a bite.
What swelling means
Local swelling can progress. Do not wait for it to “declare” severity at home.
Photograph progression only if it does not delay leaving.
This is general information, not a diagnosis. Contact your vet for anything urgent or unclear.
