Hero Dog Alerts Owner to Blood Sugar Dangers
21 Mar
Summary
- A senior dog named Dobie alerts his owner to high blood sugar.
- Dobie uses his senses to detect changes in the owner's blood sugar.
- Experts question if dogs can truly self-train as medical alert animals.
A 13-year-old retriever mix named Dobie is capturing attention for his remarkable ability to detect and alert his owner, Ronny Herndon, to dangerous blood sugar spikes. Herndon, diagnosed with Type 1 diabetes in 2020, shared a TikTok video where Dobie growls and barks to signal an elevated blood sugar level, even seeming to object to Herndon consuming coffee.
Veterinarian Dr. Julie Hunt explained that diabetes-alert dogs can detect changes in blood sugar by smelling specific compounds like isoprene or ketones on a person's breath. However, Dr. Hunt expressed skepticism regarding a dog's ability to self-train for this purpose. She noted that while dogs possess the natural olfactory capability, they would typically require owner or trainer input to understand the significance of these smells and learn alert behaviors.
Formal training for diabetes-alert dogs involves using saliva samples from individuals experiencing blood sugar fluctuations. Dogs are rewarded for correctly identifying the scent and performing an alert, such as nudging or barking. This process, while variable, can take anywhere from six months to two years to complete. While Dobie's actions are impressive, they highlight the debate around innate canine abilities versus trained medical alert skills.
