Observational study reveals no reduction in heart murmur prevalence among six-year-old Cavalier King Charles Spaniels, indicating limited early impact of the national breeding program.

Key Points

To determine the prevalence of heart murmurs caused by myxomatous mitral valve disease in six-year-old Cavalier King Charles Spaniels and assess whether the Swedish breeding program introduced in 2001 reduced murmur rates.
Sampled 353 six-year-old Cavalier King Charles Spaniels from the Swedish population, conducting cardiac auscultation on 150 dogs across two cohorts in 2007 and 2009.
Compared heart murmur prevalence between the 2007 and 2009 cohorts to assess the breeding program's impact.
Prevalence of heart murmurs was 52% (50% in females, 54% in males) in 2007 and 55% (44% in females, 67% in males) in 2009, with no significant difference between years (P=0.8).
Total heart murmur prevalence across all examined six-year-old dogs was 53% (46% in females, 61% in males), which exceeds rates documented in prior Swedish investigations.
