Luis Perez is no stranger to hardship.
At 45, he has spent much of his life battling multiple sclerosis. He lost his vision at just 23 due to complications from the disease and now undergoes regular plasma infusions to manage his symptoms. Along the way, he has also faced depression, anxiety and periods of isolation.
Hoping to improve his quality of life, Luis decided to get a guide dog — a decision that would change everything.
Through the nonprofit Dogs Inc., he was matched with a black Labrador named Jerry in September 2024. Jerry quickly became much more than a guide. He boosted Luis’s confidence, helped him reconnect socially and became a loyal companion who made everyday life brighter.
But Jerry would soon prove to be even more extraordinary.
One day, Luis began feeling unusual pain in his left leg. At first, he assumed it was related to his MS. Still, something felt different, and the discomfort worsened whenever he moved.
As he rested in his recliner, Jerry started behaving in a way Luis had never seen before. The dog repeatedly approached him and pressed his chin firmly against Luis’s leg — the exact spot where the pain was.
Concerned by Jerry’s persistence, Luis and his wife decided to go to the hospital.
After several hours of testing, doctors made a serious diagnosis: Luis had developed a deep vein thrombosis (DVT), a dangerous blood clot in his left leg — precisely where Jerry had been signaling.
DVT can quickly become life-threatening if untreated, and immediate care was critical. Luis later realized that without Jerry’s unusual behavior, he likely would have dismissed the pain as just another MS symptom and delayed seeking help.
Today, Jerry is more than a guide dog or a companion.
He’s Luis’s hero — a loyal friend who not only helps him navigate the world, but may have saved his life.
