Zero tolerance applies here. Green Onion is firmly on the toxic list for small pets and requires immediate veterinary attention if ingested. The danger lies in the natural compounds found in green onion. Thiosulfate compounds attack red blood cells, causing hemolytic anemia. Pets who ingest green onion may show symptoms within hours — though delayed reactions can make diagnosis challenging. Don't wait for symptoms. If you know your small pet ate green onion, seek veterinary help immediately.
