symptoms of pulmonary hypertension in dogs

Symptoms of canine pulmonary arterial hypertension can range from mild shortness of breath to severe respiratory failure. In the early stages, dogs may show slight breathlessness following physical activity, which can progress to coughing, lethargy, weight loss, and even fainting as the condition worsens. In extreme cases, symptoms such as ascites, hepatomegaly, and arrhythmias may emerge, correlating with the severity of pulmonary artery pressure elevation; the higher the pressure, the more pronounced the symptoms.

Tachypnea post-exercise is likely one of the initial signs, potentially stemming from increased pulmonary vascular resistance that hinders the heart's ability to effectively circulate blood through the lungs. As the disease advances, dogs may develop a dry cough, particularly noticeable at night or following exercise. Additionally, the加重的心脏负担 can lead to systemic symptoms like fatigue and weight loss. In more severe instances, syncope may occur due to the heart's failure to pump sufficient blood to the brain. Late-stage manifestations of pulmonary arterial hypertension can include ascites, hepatomegaly, and arrhythmias.

Owners should promptly seek veterinary care for dogs exhibiting these symptoms and adhere to prescribed treatments. Monitoring the dog's daily behavior and physical health is crucial, with any abnormalities warranting immediate medical attention. With a doctor's guidance, adjusting the dog's lifestyle and diet can alleviate symptoms and enhance the quality of life.
