Pulmonic Stenosis in Dogs
Pulmonic Stenosis is a medium-severity cardiac condition that can affect dogs of all ages and breeds. Pulmonic stenosis is a congenital narrowing of the pulmonary valve or surrounding tissue that restricts blood flow from the right ventricle to the lungs. Mild cases are well tolerated; severe cases cause right-sided heart failure. It is documented across 6 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Birth-2 years. Early signs to watch for include heart murmur, exercise intolerance, abdominal distension, and fainting. When treatment is required, costs are estimated at £3,000-£6,000 depending on severity, location, and the specific intervention needed. Pulmonic Stenosis has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Pulmonic Stenosis in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Heart murmur
- Exercise intolerance
- Abdominal distension
- Fainting
- Respiratory distress
Treatment Overview
Mild to moderate cases are monitored. Severe cases are treated with balloon valvuloplasty, which is highly effective in reducing the pressure gradient and improving prognosis.
Typical onset: Birth-2 years
Prevention & Screening
While not all cases of Pulmonic Stenosis can be prevented, the following steps reduce risk or enable earlier intervention:
- Cardiac clearance before breeding
- Avoid breeding affected dogs
Estimated Treatment Cost
Treatment for Pulmonic Stenosis is estimated at £3,000-£6,000, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering hereditary conditions is strongly recommended.
