Pulmonic Stenosis in Dogs 2025 – Vet Backed Symptoms, Diagnosis & Treatment 🐶

By Dr. Duncan Houston BVSc

🩒 Introduction: Understanding Pulmonic Stenosis

Pulmonic stenosis is a congenital heart defect where the flow of blood from the right ventricle to the lungs is obstructed due to narrowing of the pulmonary valve. It is one of the most common congenital heart conditions in dogs and can vary from mild to life-threatening. Early diagnosis and proper management are key to improving quality of life. 🐾

This guide includes:

• • ✅ Symptoms of pulmonic stenosis
  • 🧬 How it's diagnosed
  • 🚀 Vet-approved treatment plans and monitoring tools

1. Signs & Symptoms of Pulmonic Stenosis ⚠️

• • 😴 Exercise intolerance or lethargy
  • 🥵 Fainting or collapsing during activity
  • 😓 Labored breathing or coughing
  • 💬 Heart murmur heard on routine exam

2. Causes & Breeds at Risk 🐶

• • ✨ Congenital defect (present from birth)
  • 🐾 More common in Bulldogs, Terriers, Beagles, Boxers, and Samoyeds
  • ❓ Sometimes linked to other heart anomalies like subaortic stenosis

3. Diagnosing Pulmonic Stenosis 📅

• • ⛏️ Chest X-rays to check heart size and blood flow
  • 💼 Echocardiogram (ultrasound) to confirm valve narrowing and severity
