A life-saving alert
In the video, shared on the Instagram account "TypeONEderfulWells", the dog suddenly starts to circle his little human, who is quietly watching television.
This restlessness indicates that the dog has detected a blood sugar level that could be dangerous for the child.
After completing his mission, the dog went over to the boy to snuggle up to him. He gently rests his head on the boy's lap, as if to reassure him.
Detecting chemical changes
Known as Diabetic Alert Dogs, these dogs are trained to detect chemical changes in the human body thanks to their highly developed sense of smell.
They can identify a drop or spike in blood sugar levels even before symptoms appear or electronic devices can detect it.
