Pomeranian & Heart Disease
Pomeranians share the small-breed predisposition to MMVD. The condition develops gradually and many Poms live well into old age with monitoring and timely treatment. Like Chihuahuas, they are also predisposed to PDA, which is typically detected early in life and can often be treated surgically or with catheter-based closure.

Heart conditions in Pomeranians
Myxomatous Mitral Valve Disease (MMVD)
High riskLike many small breeds, Pomeranians are commonly affected by MMVD as they age.
Patent Ductus Arteriosus (PDA)
Moderate riskPomeranians are among the breeds predisposed to PDA, a congenital heart defect.
Screening recommendations
Start screening at
5–6 years old (or earlier if murmur detected)
Frequency
Annually once murmur is detected
Recommended tests
Cardiac auscultation, Echocardiogram
Genetic factors
Polygenic inheritance for MMVD. No specific genetic test available. Breeding dogs should be screened for heart murmurs.
Common medications
Medications are determined by your veterinarian based on your dog's individual condition. This list represents commonly used medications for this breed's typical cardiac conditions.
Prognosis
Generally good with monitoring. Many Pomeranians with MMVD live comfortably for years. Their small size means precise medication dosing is important.
