Patent Ductus Arteriosus (PDA)
Patent Ductus Arteriosus is in every mammal at birth. It is a duct that blood flows through while the fetus is still using the mother’s oxygen supply. When the baby is born and starts to breathe, this duct is supposed to close within a few hours to a few days. PDA is the most common congential heart defect in dogs. PDA may be genetic, polygenetic, or classified as a random event.
