Heartworm disease is a serious and potentially fatal condition that affects dogs. Signs of heartworm in dogs can vary depending on the stage of the disease. In the early stages, dogs may not show any symptoms. As the disease progresses, common signs include coughing, lethargy, exercise intolerance, decreased appetite, weight loss, and difficulty breathing. In severe cases, dogs may develop a swollen belly due to fluid accumulation and have a pale or bluish appearance to their gums. It's important to note that some dogs may not show any signs until the disease is advanced. Regular heartworm testing and prevention are crucial to protect your dog's health.
