My 14 pound chihuahua just ate a small amount of green onion

This answer was rated:

My 14 pound chihuahua just ate a small amount of green onion (maybe 1 tsp). Should I induse vomiting or watch her. She has no digestive problems and seems to have an iron stomach with other things she has found to eat.

Hello. Thanks for writing in.

How long ago did this ingestion occur?

Customer: replied 4 years ago.

10 minutes or so

Thanks for the information. Normally we don't worry much about onion toxicity in dogs unless they consume large amounts at one time or consume smaller amounts consistently. He would have to consume anywhere from 100-200 grams of onions to cause a concern. To be on the safe side, I would give her a tablespoon (15ml) of 3% hydrogen peroxide orally to induce vomiting. I would then watch her for any weakness, extreme lethargy, shivering or pale gums. If any of those issues are noted, I would have your vet evaluate her. I don't expect any issues, though. Please let me know if you have any other questions. Hope this helps.

Thank you for the follow up. Lizi is doing fine. No adverse effects from the onions and I watch my plate closer now. Thank you for your assistance.
