## 根因

洋葱含有N-丙基二硫化物，会氧化损伤血红蛋白，导致狗出现海因茨体溶血性贫血，单次剂量为体重的0.5%即可中毒。

## 解决方案

1. ```
   Immediately stop feeding onions and administer vitamin E (10 IU/kg) and selenium (0.1 mg/kg) orally to support red blood cell health, then monitor for pale gums and lethargy. Example: 'Crush a 400 IU vitamin E capsule and mix with food.'
   ```
2. ```
   If anemia is confirmed (PCV below 30%), emergency vet treatment includes blood transfusion and oxygen therapy, plus N-acetylcysteine (50 mg/kg IV) to counteract oxidative damage. Example: 'Request a packed red blood cell transfusion if PCV drops below 20%.'
   ```

## 无效尝试

- **** — Some believe cooking onions destroys the toxin, but N-propyl disulfide is heat-stable and remains toxic even after boiling or baking. (85% 失败率)
- **** — Owners think small amounts daily are safe, but chronic low-dose exposure causes cumulative oxidative damage and delayed anemia. (90% 失败率)
- **** — Using onion powder as a supplement is equally dangerous, as concentrated forms have higher toxicity per gram. (95% 失败率)
