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. 🐾
