When the heart weakens, the body struggles to keep pace.
Heart Disease
Heart disease in dogs refers to a range of conditions that affect the heart’s ability to pump blood effectively. Common forms include valvular disease (such as mitral valve disease), dilated cardiomyopathy, and congenital defects.
Small breeds often suffer from chronic valvular disease, while large breeds are more prone to cardiomyopathy. Symptoms usually develop gradually, but early recognition is vital to prolong life and improve comfort.
The heart is the silent engine – when it falters, every part of the dog’s body feels the strain.
Core signs of Heart Disease include:
- Persistent coughing, especially at night
- Exercise intolerance or fatigue
- Rapid or laboured breathing
- Fainting or collapse
- Swollen abdomen from fluid accumulation
While heart disease cannot usually be cured, early treatment, lifestyle changes, and medication can extend life and improve wellbeing.
