Puppy Heart Murmurs: Essential Guide for Breeders
Murmurs demand careful listening, not guesses
Congenital heart disease in puppies is often detectable early via murmur type, grade, and context, but cannot be diagnosed reliably by auscultation alone—echocardiography by the right specialist is the key decision point.
A grade-one murmur is usually noise, not risk
Low-grade murmurs can reflect normal early turbulence from puppy anemia and may resolve, so recheck in one to two weeks—yet grade-one can sometimes worsen, so missing it is still costly.
“Fixable” PDA doesn’t justify breeding it
PDA is comparatively correctable (catheter closure, often school-based) and can restore normal life expectancy, but other congenital defects have poor or lifelong-managed outcomes; breeding only echocardiogram-clear stock reduces—never eliminates—risk.
