## Root Cause

Both NSAIDs like ibuprofen and acetaminophen cause gastrointestinal bleeding, liver necrosis, and kidney failure in dogs at human doses; AI often confuses them or fails to cite veterinary-specific dosing.

## Workarounds

1. **Replace with: 'Never give human pain relievers to dogs. For pain, consult a vet immediately. Safe options include veterinary-prescribed carprofen (Rimadyl) or meloxicam (Metacam) at 0.1-0.2 mg/kg once daily after food.'** (95% success)

2. **If user asks about pain management, respond: 'Only use vet-prescribed NSAIDs like carprofen. For mild pain, apply cold packs (15 min on/off) and restrict activity. Never use ibuprofen, acetaminophen, or aspirin without vet guidance.'** (93% success)

## Dead Ends

- **Suggesting half a human ibuprofen tablet for small dogs** — Dogs metabolize NSAIDs differently; even 5mg/kg can cause ulcers; veterinary carprofen is safer (98% fail)
- **Recommending acetaminophen as safer alternative to ibuprofen** — Acetaminophen is also toxic to dogs, causing methemoglobinemia and liver failure; no safe OTC dose (90% fail)
