- Difficulty breathing
- Exercise intolerance
- Spitting up blood
- Bluish or purplish skin

Causes Of Pulmonary Hypertension In Dogs
There are several possible causes of pulmonary hypertension in dogs. Conditions that affect the lungs, heart, or blood can all lead to pulmonary hypertension. It is important to get a veterinary diagnosis so that the underlying cause can be treated. Here are a few possible causes of pulmonary hypertension in dogs.
- Blood vessel obstruction
- Adult respiratory distress syndrome
- Adrenal gland problems
- Kidney disease
- Pancreatic inflammation
- Immune-mediated diseases
- Heart disease
- Living at high altitudes
Treatments For Pulmonary Hypertension In Dogs
Treatment for pulmonary hypertension in dogs depends on the severity of the condition and the underlying causes. If a dog is having severe breathing difficulties, they may be hospitalized and given oxygen therapy, as well as medication to make breathing passages dilate to allow more air to pass through. Other medications may help remove fluid from the lungs or treat congestive heart failure.
Once symptoms are under control, care should continue at home. This includes keeping dogs in a stress-free environment and reducing physical pressure. Dogs with pulmonary hypertension should avoid extreme cold or heat, dry hair, secondhand smoke, and high altitudes. Physical activity might need to be restricted, and a low sodium diet may be prescribed.
If there are underlying causes of pulmonary hypertension that have been identified, those may need to be treated, as well. Treatment for infections may include antibiotics or other medications, diseases of the kidneys, heart, adrenal glands, and immune system will require strict monitoring and care, and heartworm and some forms of cancer may need surgical treatment.
Dogs with pulmonary hypertension will need follow-up veterinary examinations to monitor blood pressure and make sure the heart is functioning properly. Damage to the heart or lungs may be irreversible, and treatment may focus more on making dogs comfortable than curing the condition.
