Rat poison: when to go to the ER
Unknown bait plus a sick pet: ER. Known bait plus a stable pet: hotline and clinic instructions — which often still mean go.
Do this first
| Scenario | Rodenticide (rat/mouse bait) ingestion |
|---|---|
| Vet vs poison control vs ER | Always call poison control first when the bait type is unknown — anticoagulant, bromethalin, cholecalciferol, and zinc phosphide require different plans. Then follow clinic or ER instructions. Bleeding, seizures, or sudden collapse means ER now. |
Immediate action steps
- ER now for bleeding, breathing distress, seizures, or collapse
- Call poison control with the label when the pet is stable enough for a short triage call
- Follow their instruction to present to a clinic — do not bargain it into tomorrow
- Bring packaging
- Secure remaining bait
Unknown product raises urgency
If you cannot identify the bait, emergency clinicians can still start evaluation while identification continues.
Photograph shelves and storage bins if the box is missing.
Why “my dog looks fine” fails for some baits
Delayed mechanisms exist. Looking fine is a moment in time, not a toxicology clearance.
Ask the hotline what monitoring or bloodwork window applies to that ingredient.
This is general information, not a diagnosis. Contact your vet for anything urgent or unclear.
