Patent ductus arteriosus, or PDA, is a heart defect that presents in young dogs. It develops shortly after birth, and though it is a serious condition, it can be successfully treated with surgery.



Development

PDA develops when a specific blood vessel used by the fetus during pregnancy doesn't close off after birth. It creates an abnormal blood flow in the dog's heart.
Risk Factor

PDA is the most common congenital heart defect found in dogs, and it is more common in females. At-risk breeds include Pomeranians, German shepherds, Yorkshire terriers, chihuahuas and others.
Early Signs

Coughing, weight loss and decreased tolerance of exercise are all symptoms of PDA in dogs. Eventually it escalates into congestive heart failure and probable death.
Treatment

Surgery should be performed as early as possible---dogs as young as 8 weeks are able to undergo the procedure. The operation ties off the blood vessel in question.
Survival and the Future

When recognized and treated early in life, the rate of survival for dogs with PDA is typically very good. Owners are advised not to breed dogs that have suffered from PDA.
