Legally blind man kept dismissing dog's strange nudges, until a doctor confessed he had just saved his life
The dog stopped following Perez’s commands, stopped doing any work, and just kept sitting right next to him all the time
Florida resident Luis Perez was puzzled when his guide dog, Jerry, began acting strangely. The normally calm black Labrador started behaving in ways Perez couldn’t understand, repeatedly trying to get his attention and refusing to settle down. Concerned that something might be wrong, Perez eventually went to see a doctor. That visit revealed a shocking truth: Jerry’s unusual behavior had been warning him about a serious medical issue, one that could have cost him his life, reported PEOPLE on March 24.
Perez started to notice that Jerry's behavior seemed to change to the point that it left Perez and his wife concerned. One day, Perez was resting on a recliner when he felt a pang of pain in his left leg. He wanted to get up, but found that he couldn’t. Jerry got up, lowered its chin, and pressed it down on his leg. The pressing was a normal gesture. Every time Perez felt pain, was anxious or stressed, Jerry pressed his chin to soothe him and provide grounding. What wasn’t normal this time was that Jerry wouldn’t just get up. “He kept doing it, and he wouldn’t let me stand up,” Perez recalled. "He's never done this before. He doesn't want to let me stand up. He doesn't want to let me walk," Perez was forced to wonder.
Over the next few days, the dog’s behavior turned even more defiant. He stopped following Perez’s commands, stopped doing any work, and just kept sitting right next to him all the time as if he hadn’t seen him for a long time. "He kept bothering me and bothering me and bothering me until I couldn't take it anymore because I got anxious because he was getting anxious," Perez recalled. Concerned, he finally visited a doctor.
The medical report diagnosed Perez with “deep vein thrombosis (DVT),” a condition that leaves a blood clot in a deep vein in the leg. This clot can travel to the lungs and eventually the heart, causing death. "It ended up being a big blood clot, and it could have killed me," Perez described. Through the four days Perez spent in the hospital for treatment, Jerry stayed by his side. If it weren't for Jerry, Perez could have just died.
Perez had already been navigating major challenges long before Jerry entered his life. By the age of 23, two autoimmune disorders had begun damaging his vision, and by 47, he was legally blind. Living alone during the day while his family worked, he often struggled with falls and daily tasks. After two particularly bad falls, he contacted the guide dog organization Dogs Inc. In September 2024, the organization matched him with Jerry, a five-year-old black Labrador trained to help people with vision loss.
After Jerry entered his life, Perez felt a connection so deep he had never felt with any other animal. He started taking technology classes, visiting the mall on his own, and flying to Colorado Springs to meet his daughter and grandchildren, all things that had made him uncomfortable earlier. Not only his lifestyle, but his emotional health also began to improve. Poor eyesight had led him into a consistent frequency of anxiety and depression, but once Jerry came, these feelings started dissolving away. "He helps me out, man, tremendously,” Perez professed.
Perez is not the only person who was saved by his dog. A 2018 study published in the American Heart Association Journal revealed that owning a dog has significant and positive effects on the owner. Researchers found that dog ownership is associated with a 33% lower risk of premature death for heart attack survivors and a 27% reduced risk of early death for stroke patients, compared to people who don't own a dog. Dogs, researchers said, were also found to help the owners heal from social isolation, anxiety, and stress, exactly what Jerry demonstrated.
Today, their bond is stronger than ever. They go to the gym, cook meals, and explore parks and museums, having a ball together. Jerry is the poetry of Perez’s life: “He’s an angel wrapped in fur.”
