Health & Common Issues

Mitral Valve DiseaseThe breed's defining health concern — a heart condition affecting a large proportion of Cavaliers, usually appearing in middle age, that requires regular cardiac monitoring.

SyringomyeliaA neurological condition linked to the breed's skull structure, causing pain or sensitivity in some individuals.

Ear InfectionsTheir long, floppy ears trap moisture, making regular cleaning an important preventive habit.

Training & Exercise

Use gentle, positive reinforcement — Cavaliers are eager to please and respond very well to reward-based methods.
Establish a consistent veterinary cardiac screening schedule from early adulthood, given the breed's well-documented heart health predisposition.
Socialize widely, though most Cavaliers are naturally sociable and adapt easily to new people, pets, and environments.
Avoid leaving alone for long stretches, since their strong attachment to people can lead to separation anxiety without gradual conditioning.
