| Condition | Prevalence | Onset | Severity | Screening |
|---|---|---|---|---|
| Calcium Oxalate Urolithiasis | One of the highest-risk breeds | 5-10 years | SEVERE | Urinalysis twice yearly from age 4. Imaging for any straining, hematuria or repeated "cystitis" — a male Bichon straining to urinate is an emergency until proven otherwise. |
| Early-Onset (Juvenile) Cataracts | Elevated | 1-5 years | MODERATE RISK | Annual CAER ophthalmic examination from age 1. |
| Patellar Luxation | 15-25% | 4-6 months | MODERATE RISK | Orthopedic exam at 6 months and annually; grade both stifles. |
| Atopic Dermatitis | Common | 6 months-3 years | MODERATE RISK | Rule out flea allergy and food trial first; intradermal or serum allergen testing only once secondary infection is controlled. |
| Periodontal Disease | Very common | 2-5 years | MODERATE RISK | Oral exam annually; anesthetic COHAT with full-mouth radiographs — small-breed disease is largely subgingival and invisible on a conscious exam. |
