Cavalier King Charles Spaniel
Small, soft, sweet — and saddled with two genetic heart issues.
Cavaliers are companion dogs in the truest sense. They struggle when alone for long stretches and bond hard. Their genetic burden is real — mitral valve disease and syringomyelia together affect a heartbreaking proportion of the breed. Choose a breeder who tests both.
What makes them, them
- 13–18 lb adult; medium-length silky coat.
- Mitral valve disease begins in many Cavaliers by age 5 — annual cardiac auscultation a must.
- Syringomyelia: chiari-like skull malformation, MRI-screenable in breeding stock.
- Sweet-tempered with everyone — including burglars.
Safety — what actually goes wrong
- Never trust the breed for guard duty — they will greet a stranger like a friend.
- Watch for syncope (fainting) — sometimes the first sign of cardiac decline.
- Microchip + Boop tag; a wandering Cavalier will follow anyone holding food.
