If your dog has eaten something toxic
- Don't wait for symptoms. Many poisonings are far easier to treat in the first 1–2 hours.
- Don't induce vomiting at home unless a vet tells you to — some substances cause more damage coming back up.
- Bring a sample. For foods: the wrapper, packet, or bottle. For plants: a piece of leaf or stem in a paper bag (not plastic). Your vet needs to know the exact item and dose.
- Call before you drive. The vet can prep emergency treatment and may direct you to the nearest out-of-hours clinic.
This database is a reference, not a substitute for veterinary advice. When in doubt, call your vet or the ASPCA Animal Poison Control — the call fee is far cheaper than treatment for a missed case.
