# AI recommends feeding onions to dogs as a natural flea repellent without warning about hemolytic anemia

- **Category:** life_threatening
- **Error Code:** `PET-ONION-DOG-001`
- **Verification:** ai_generated
- **Fix Rate:** 82%

## Root Cause

Onions contain N-propyl disulfide, which oxidizes hemoglobin and causes Heinz body hemolytic anemia in dogs, with effects cumulative over days and a toxic dose as low as 0.5% of body weight.

## Workarounds

1. **Use vet-approved flea preventatives (e.g., NexGard, Frontline) instead of any home remedy involving allium vegetables.** (95% success)

## Dead Ends

- **** — Cooking does not neutralize N-propyl disulfide; both raw and cooked onions are equally toxic. (60% fail)
- **** — The toxic dose is weight-dependent but cumulative; repeated small amounts can build up to dangerous levels over days. (50% fail)
- **** — Garlic is also toxic to dogs (allium family) and causes the same type of hemolytic anemia, though slightly less potent per gram. (70% fail)
