Puff, a Maltese-Shih Tzu mix who weighs only 2.5 kg. (about five and a half pounds), suffered from patent ductus arteriosus (PDA), the most common congenital cardiovascular defect of dogs. PDA leaves an opening between the pulmonary artery and the aorta. Without a surgical procedure that can only be performed by board-certified veterinary cardiologists at the University of Minnesota Veterinary Medical Center, the 4-month-old dog would likely die of heart failure within a year. The life-saving procedure is considered curative.
Before the procedure, Puff appeared completely normal, was very athletic, and “could outrun all other dogs at the dog park,” says Shannon from Underdog Rescue, where Puff lives. The surgery was performed by Dr. Chris Stauthammer, a board-certified veterinary cardiologist who says that Puff will be able to resume a normal life much like she had before the surgery.
