Heart Health and the Pekingese

Quick answer

The Pekingese is a breed that shows a recognised tendency toward Myxomatous Mitral Valve Disease. While this is a common concern for smaller breeds, proactive monitoring at home and regular checkups with your vet allow you to catch changes early, which is the best way to manage heart health effectively.

Understanding Myxomatous Mitral Valve Disease

Myxomatous Mitral Valve Disease is a condition where the valves inside the heart do not seal as tightly as they should. This is a recognised tendency in the breed. Over time, this change can cause the heart to work harder to pump blood throughout the body. Because this is a recognised tendency rather than a proven one, it is important to understand that not every dog will develop clinical signs, but being aware of the possibility allows for earlier intervention.

At home, you might first notice your dog becoming more tired than usual during walks or showing less interest in play. You may also observe a persistent cough, especially at night or when your dog is resting. If you notice these signs, your vet will perform a physical exam using a stethoscope to listen for a heart murmur. This sound indicates that blood is flowing turbulently through a valve that is not closing perfectly. If a murmur is detected, an ultrasound of the heart, known as an echocardiogram, is the test that settles the diagnosis and helps determine the severity of the condition.

Home Monitoring and Care

Caring for a Pekingese with a potential heart condition requires consistent observation. You should create a simple monthly exam routine. For senior dogs, perform this check weekly. Check their body condition score, inspect their gum color, observe their mobility, monitor their breathing at rest, check the skin and coat, and note any changes in behavior. If you see something concerning, take a short video clip. A video of abnormal breathing or gait is often more helpful to your vet than a verbal description.

Managing Heart Health

One common mistake owners make is waiting until a dog is clearly exhausted or struggling to breathe before seeking an evaluation. If you suspect your dog has a heart issue, do not wait for the next annual checkup. A vet will assess the urgency based on the presence of clinical signs like coughing or lethargy. If your dog is diagnosed with a heart condition, your vet will discuss the appropriate management plan, which may include dietary adjustments or specific medications to support heart muscle function.

Consistency is your greatest tool. By maintaining a log of your dog's health markers and staying observant during your routine home exams, you provide your vet with the best information to keep your Pekingese comfortable for as long as possible.
