Pulmonic Stenosis in Dogs

Pulmonic Stenosis, also referred to as Congenital Heart Defect, is the third most common congenital heart disease in dogs.

Pulmonic stenosis refers to a constriction of the pulmonic heart valve through which blood must pass from the heart to the lungs. Most affected dogs initially show no symptoms even though a heart murmur might be present. These types of murmurs are typically noted on routine veterinary examinations with a stethoscope.

As the disorder progresses the right side of the heart eventually fails and is unable to accommodate the blood flow. This leads to edema or fluid build-up within the abdomen and limbs.


Treatments include medication, balloon valvuloplasty or surgery depending on the severity and health of the dog.

Cost to Treat: $15,000 to $20,000

Heart surgery for dogs is very expensive. Costs range from $15,000 to over $20,000 depending on the type of surgery and where you live.
