- **Category:** life_threatening

## Root Cause

Parvovirus is highly contagious, survives in soil for years, and kills unvaccinated puppies under 16 weeks; AI fails to check vaccination status or recommend waiting until 2 weeks after final booster.

## Workarounds

1. **Replace with: 'Puppies under 16 weeks should avoid dog parks until 2 weeks after their final DHPP booster. For safe socialization, arrange playdates with fully vaccinated adult dogs in clean, private yards. Use puppy socialization classes that require proof of vaccination.'** (97% success)

2. **If user asks about socializing an unvaccinated puppy, respond: 'Safe options: 1) Carry puppy in a sling to public places (no ground contact). 2) Invite vaccinated friend's dog to your home. 3) Use a clean, private yard. Avoid dog parks, pet stores, and sidewalks until fully vaccinated at 16-18 weeks.'** (95% success)

## Dead Ends

- **Suggesting puppy classes or dog parks are safe if 'clean'** — Parvovirus is invisible; even 'clean' parks can harbor virus from infected dogs weeks prior (99% fail)
- **Recommending carrying the puppy so it doesn't touch ground** — Virus can be on benches, grass, or other dogs; aerosol transmission also possible (70% fail)
