There are numerous harmful toxins generated from onions, the most prominent of which is N-[1-propenyl]propyl disulfide. Onions also contain other types of sulfides, such as thiosulfinates and thiosulphates.

The dogs that ingest the majority of the onions will have a high risk of death.

If not treated, HA will lead to death within a few days. If dogs survive the first week or so after the onset of HA, they may live with chronic anemia for months to years if they lose all their red blood cells. Often the only way to determine if a dog has ingested onions is through an examination of stool or vomit samples.
