Shih Tzu Cardiomyopathy: What You Need to Know
Shih Tzu cardiomyopathy is a serious heart condition affecting many of these affectionate dogs.

What you can try
- Ensure a balanced diet that is appropriate for your Shih Tzu's size and age. Consult your vet for recommendations on high-quality dog food.
- Maintain a regular exercise routine to keep your dog active without overexerting them. Short walks and playtime in a safe space can be beneficial.
- Monitor your dog's weight closely and adjust their diet or exercise as needed to prevent obesity, which can strain their heart.
- Create a calm home environment to reduce stress. Consider using calming music or pheromone diffusers to help your Shih Tzu relax.
Mistakes that make this worse
Avoiding these common mistakes can help manage Shih Tzu cardiomyopathy more effectively.
- Neglecting Regular Vet Visits: Skipping check-ups can lead to missed signs of worsening heart health. Schedule regular visits to catch issues early.
- Ignoring Symptoms: Dismissing signs like coughing or lethargy can delay treatment. Pay attention to any changes in behavior and consult your vet promptly.
- Inconsistent Medication: Not giving prescribed heart medications regularly can worsen the condition. Create a schedule to ensure your Shih Tzu gets their meds on time.
- Overexertion During Play: Allowing vigorous play can strain the heart. Opt for gentle activities and limit exercise to what's recommended by your vet.
- Poor Diet Choices: Feeding low-quality food can impact heart health. Stick to vet-recommended diets that support heart function and overall health.
- Stressful Environments: Exposing your Shih Tzu to high-stress situations can exacerbate symptoms. Create a calm home environment to help them feel secure.
