## 解决方案

1. ```
   Use veterinary-approved flea preventatives like nitenpyram (Capstar) or spinosad (Comfortis), applied or given as directed.
   ```
2. ```
   If a dog has ingested garlic, monitor for pale gums, weakness, or dark urine; immediately seek veterinary care for blood tests and possible oxygen therapy.
   ```
3. ```
   For natural alternatives, use diatomaceous earth (food grade) on carpets and bedding, but avoid inhalation and keep away from eyes.
   ```
