Rescue Dog’s Unusual Behavior Leads to Owner’s Brain Aneurysm Diagnosis
A Missouri woman credits her rescue dog, Sunny, with alerting her to a life-threatening medical condition. Kenzie Kinney Seymour, 31, discovered she had a brain aneurysm after Sunny exhibited increasingly anxious and persistent behavior, fixating on her neck just one day before diagnosis.
Seymour shared her story on social media, detailing how Sunny, a Brittany–Keeshond mix, began acting unusually clingy and wouldn’t leave her side. A video of the incident, which has garnered thousands of views, shows Sunny pressing her head and body against Seymour’s neck and shoulders while she was in bed. The accompanying text read: “The day before I was diagnosed with a brain aneurysm, my dog kept climbing behind me and wouldn’t leave my neck alone.”
“I don’t know that she predicted it, but she could sense something was wrong,” Seymour told Newsweek. “She wouldn’t stop whining, licking excessively, hovering and laying behind me, propping herself on my back, neck and shoulders.”
This wasn’t an isolated incident. Seymour explained that Sunny has a history of reacting to her health issues, including a leg affected by chronic blood clots. “She does the same thing with my leg that has permanent chronic blood clot damage,” Seymour said. “It is always nerve-wracking when Sunny gets so antsy like that, because it’s not normal for her and I know she is sensitive to my health problems.”
Can Dogs Detect Illnesses?
While there is currently no scientific evidence to support the claim that dogs can detect unruptured brain aneurysms, research suggests they possess an extraordinary ability to identify subtle changes in the human body. Studies have demonstrated that medical detection dogs can be trained to detect a range of illnesses, from various cancers to COVID-19.
A 2022 study revealed that medical detection dogs could identify COVID-19 in sweat samples with approximately 98 percent sensitivity and 92 percent specificity. Further bolstering this idea, a 2021 study conducted by Queen’s University Belfast found that pet dogs reacted differently to sweat samples taken from individuals during epileptic seizures compared to samples taken when they were not seizing, suggesting they can detect a specific seizure-related odor.
This isn’t the first anecdotal evidence of a dog’s remarkable intuition. In 2022, a woman in Dublin, Ireland, shared how her dog, Sox, alerted her family to her father’s cancer before any medical diagnosis. Another dog, Gus, a medical alert and response service dog in training (SDiT), gained viral attention for his ability to identify gluten in food with a single sniff.
Concerned by Sunny’s persistent and unusual behavior, Seymour sought medical attention, experiencing intense head and neck pain. Initially, medical staff considered discharging her, but Seymour insisted on undergoing a CT scan. The scan subsequently revealed the presence of a brain aneurysm.
Seymour is now awaiting consultation with a neurologist, taking her recovery “day by day.” She shared her experience on Instagram, where it has already been viewed over 10,000 times. The comments section is filled with similar stories from other pet owners.
“I had a similar experience recently with a non-trained dog alerting to me. She was able to predict an episode of syncope before I even felt it and potentially saved me… Dogs are so so cool,” one commenter wrote. Another shared, “Scottie did this with my seizures… dogs are such a gift!” A particularly poignant comment read: “Everyone is taught that angels have wings, but the lucky ones of us find they have four paws.”
While Sunny may not be a formally trained medical-alert dog, Seymour is immensely grateful for her canine companion’s unwavering vigilance and the crucial role she played in her diagnosis. Seymour is delighted to have Sunny by her side, always keeping a watchful eye on her health.
