At 6 months old, Rex was by far the calmest dog the Silverman family of New York had ever owned. Their other German shepherds all bounced off the walls at that age, so at first they attributed Rex's docile behavior to temperament.

Dr. Singletary told Silverman that Rex was a candidate for radiofrequency catheter ablation, where small areas of the heart muscle are heated through the tip of a catheter to destroy abnormal tissue.
