Dachshund & Heart Disease

Myxomatous Mitral Valve Disease (MMVD)

Dachshunds are among the small breeds most commonly affected by MMVD. The disease follows the typical pattern of progressive valve degeneration, starting with a soft heart murmur and potentially progressing to heart enlargement and congestive heart failure over years. Many Dachshunds live full lives with careful monitoring and timely treatment.

Heart conditions in Dachshunds

Myxomatous Mitral Valve Disease (MMVD)

High risk

MMVD is very common in Dachshunds, particularly in middle-aged and older dogs. One of the most frequently affected breeds.

Screening recommendations

Start screening at

5–6 years old (or earlier if murmur detected)

Frequency

Annually once murmur is detected (echocardiogram)

Recommended tests

Cardiac auscultation, Echocardiogram

Genetic factors

Polygenic inheritance, similar to other small breeds affected by MMVD. No specific genetic test is available.

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

Similar to other small breeds with MMVD. Stage B1 dogs often remain stable for years. Prognosis after CHF onset depends on response to treatment but many do well for 1–2+ years.
