Cavalier King Charles Spaniels are highly sensitive to heat because their short muzzles make it difficult for them to pant efficiently and cool down.

Vet Insights

Cavalier King Charles Spaniels are exceptionally affectionate but face a significant genetic risk for Mitral Valve Disease (MVD), which affects over 50% by age five and nearly all by age ten. As a veterinarian, I prioritize annual cardiac screenings by a specialist starting at age one to detect heart murmurs early. This breed is also predisposed to syringomyelia (SM), a painful neurological condition, as well as hip dysplasia, patellar luxation, and eye issues. To manage these risks, it is critical to maintain a lean body weight to reduce heart strain, avoid overexertion in heat, and secure comprehensive pet insurance early in life. Early intervention with medication and specialized care is essential to prolonging their quality of life.
