Pet Insurance Pre-Existing Conditions: Complete Guide (2026)
⚡ Quick Answer
Most pet insurance companies do not cover pre-existing conditions — health issues that showed symptoms before your policy started. However, some providers distinguish between "curable" and "incurable" conditions, covering curable ones after a 12-month symptom-free period.
Key Takeaways
- Pre-existing conditions are the #1 reason claims are denied
- “Curable” conditions (ear infections, UTIs) may be covered after 12 months symptom-free
- “Incurable” conditions (diabetes, cancer, allergies) are permanently excluded
- Getting insurance before health issues develop is the best strategy
- Some providers are more lenient than others with borderline conditions
