## 根因

小苏打（碳酸氢钠）pH值约8.3，对狗皮肤（正常pH 5.5-7.5）呈强碱性，破坏酸性保护膜，导致刺激、干燥和继发感染。

## 解决方案

1. ```
   使用兽医认可的燕麦基洗发水（如'Vet's Best Allergy Itch Relief Shampoo'），其pH值适合狗。示例：'涂抹在湿毛上，揉搓5分钟，彻底冲洗。每周重复。'
   ```
2. ```
   对局部瘙痒区域冷敷（干净布浸凉水）10-15分钟，然后拍干。可舒缓而无化学刺激。示例：'不要摩擦，轻轻按压。'
   ```

## 无效尝试

- **** — Adding water to baking soda to make a paste does not neutralize the pH; it remains alkaline and still damages skin. (40% 失败率)
- **** — Using baking soda in a bath as a soak is still irritating because the entire skin surface is exposed to alkaline solution, worsening dermatitis. (30% 失败率)
