Shauna Darcy got Ruby as a service dog for anxiety, but the pup became her lifeline. Ruby’s training helped detect Shauna’s rare heart condition, POTS, by sensing changes in her heart rate and blood pressure. She assisted with panic attacks, fetched medications, and provided constant support.
One day, Ruby alerted Shauna to an emergency before symptoms appeared. Trusting her dog, Shauna called an ambulance just before collapsing. Doctors found her heart in atrial fibrillation, but Ruby never left her side, staying with her in the hospital and ultimately saving her life.
