## 根因

细小病毒和犬瘟热病毒高度传染性，可在土壤中存活多年；16周以下未接种疫苗的幼犬没有免疫力，感染后死亡率超过80%。

## 解决方案

1. ```
   Wait until the puppy has completed the full DHPP vaccine series (typically at 16 weeks) plus a 2-week waiting period for full immunity. Example: 'Schedule the final booster at 16 weeks and wait 2 weeks before any public outings.'
   ```
2. ```
   For safe socialization before full vaccination, host controlled playdates with fully vaccinated, healthy adult dogs in a clean, private yard. Example: 'Invite a friend's vaccinated dog to your home after disinfecting the yard with a 1:30 bleach solution.'
   ```

## 无效尝试

- **** — Owners think carrying the puppy prevents exposure, but parvo can be transmitted via shoes, clothing, and surfaces that the puppy later contacts. (90% 失败率)
- **** — Some believe a single vaccine dose at 8 weeks provides full protection, but maternal antibodies can interfere with vaccine efficacy until the booster series is complete at 16 weeks. (85% 失败率)
- **** — Choosing a 'clean' park with few dogs is still risky, as parvo can survive in contaminated soil for up to 5 years regardless of current dog traffic. (80% 失败率)
