1. **Coughing**: A persistent cough, especially at night or after exercise, can be a sign of heart disease. This occurs due to fluid buildup in the lungs.
2. **Difficulty Breathing**: If your dog shows signs of labored breathing or seems to be struggling to catch their breath, it could indicate heart issues.
3. **Fatigue**: Dogs with heart disease may tire easily during walks or playtime. They might seem less enthusiastic about their usual activities.
4. **Weight Loss**: Unexplained weight loss can be a sign of heart disease, especially if accompanied by a decreased appetite.
5. **Swollen Abdomen**: Fluid accumulation in the abdomen (ascites) can cause a noticeable swelling, which may indicate heart failure.
6. **Fainting or Collapse**: If your dog faints or collapses, it could be due to inadequate blood flow caused by heart problems.
7. **Blue-tinged Gums or Tongue**: Cyanosis, or a bluish tint to the gums or tongue, can indicate a lack of oxygen in the blood due to heart disease.
If you notice any of these symptoms, it is crucial to consult a veterinarian for a proper diagnosis and treatment plan. Early detection can make a significant difference in managing heart disease in dogs.
