1. **Coughing**: A persistent cough is often one of the first signs of heartworm disease. It may be dry or productive and can worsen with exercise.
2. **Fatigue**: Infected dogs may tire easily during walks or playtime. They might seem less enthusiastic about activities they once enjoyed.
3. **Weight Loss**: As the disease progresses, dogs may lose weight despite having a normal appetite.
4. **Difficulty Breathing**: As heartworm disease affects the lungs, dogs may exhibit labored or rapid breathing, especially during physical activity.
5. **Swollen Abdomen**: In advanced cases, fluid may accumulate in the abdomen, leading to a noticeable swelling.
6. **Pale Gums**: A dog's gums may appear pale or bluish due to reduced oxygen levels, which can be a sign of severe heartworm infection.
7. **Fainting or Collapse**: In severe cases, dogs may faint or collapse due to decreased blood flow and oxygen to the organs.
If you notice any of these signs in your dog, it’s important to consult your veterinarian immediately for diagnosis and potential treatment. Preventative measures, such as monthly heartworm medication, are also essential in keeping your dog healthy and safe from this disease.
