## Root Cause

Onions (and garlic, leeks, chives) contain N-propyl disulfide and thiosulfates that damage canine red blood cells, causing Heinz body hemolytic anemia; toxicity is dose-dependent but cumulative.

## Workarounds

1. **If ingestion occurs, induce vomiting if within 2 hours, then monitor for anemia symptoms (pale gums, lethargy, dark urine) for 3-5 days; vet may prescribe antioxidants (e.g., N-acetylcysteine) or blood transfusion if severe** (75% success)

2. **Use dog-safe flavor enhancers: low-sodium chicken broth (no onion), parsley, or dog-safe commercial toppers** (95% success)

## Dead Ends

- **** — Cooking does not destroy the toxic compounds; both raw and cooked onions are equally dangerous (85% fail)
- **** — Toxic dose is 0.5% of body weight (e.g., 0.5 oz onion for 10 lb dog); cumulative exposure over days can also cause anemia (80% fail)
- **** — Onion powder is concentrated; even 1 tsp can be toxic to a small dog (90% fail)
