## 根因

狗皮肤pH值为5.5-7.2（中性至微酸性）；小苏打（pH 9）破坏酸性保护膜，导致皮肤碱中毒，加重炎症，促进细菌或酵母菌过度生长。

## 解决方案

1. ```
   Use a veterinary-approved oatmeal-based shampoo (e.g., Aveeno, DermAllay) with colloidal oatmeal, which soothes itching without disrupting pH. Bathe with lukewarm water, rinse thoroughly.
Example: Apply 1 oz shampoo per 10 lbs body weight, lather for 5-10 minutes, rinse until water runs clear. Repeat every 7-14 days as needed.
   ```
2. ```
   For localized itching, apply a cold compress (damp cloth in freezer for 10 min) directly to itchy area for 5-10 minutes, then dry. Use an Elizabethan collar to prevent licking.
Example: Use a clean washcloth, wet with cool water, freeze 10 min, apply to hotspot for 5 min, repeat every 4 hours. Consult vet for antihistamines if needed.
   ```

## 无效尝试

- **** — Using baking soda as a dry shampoo between baths — powder can be inhaled causing respiratory irritation, and residue remains on skin for hours. (70% 失败率)
- **** — Mixing baking soda with water to make a rinse — still alkaline; repeated use erodes skin barrier over weeks. (65% 失败率)
- **** — Applying to hot spots thinking it will dry them out — baking soda delays healing by inhibiting fibroblast migration in wounds. (75% 失败率)
