1. **Coughing**: A persistent cough, especially at night or after exercise, can indicate fluid in the lungs or other heart-related issues.
2. **Difficulty Breathing**: If your dog seems to struggle to catch their breath, pants excessively, or exhibits labored breathing, this could be a sign of heart disease.
3. **Fatigue or Weakness**: If your dog is less active than usual, tires easily during walks, or shows reluctance to play, it could indicate heart problems.
4. **Loss of Appetite**: A sudden change in eating habits, such as refusing food or eating significantly less, can be a warning sign.
5. **Weight Loss**: Unexplained weight loss, even if your dog is eating normally, might be a concern.
6. **Swollen Abdomen**: Fluid accumulation in the abdomen can cause swelling, which may indicate heart failure.
7. **Fainting or Collapsing**: If your dog experiences fainting spells or collapses, this is an emergency and requires immediate veterinary attention.
8. **Blue-tinged Gums**: Gums that appear bluish or pale can indicate inadequate oxygenation due to heart issues.
If you notice any of these signs, it's essential to consult your veterinarian as soon as possible for a thorough examination and appropriate testing. Early intervention can significantly improve your dog's quality of life and longevity.
