The story takes place in Ottawa, Canada. There, a woman was walking with her dog through the streets of the city and at that time she had a seizure, due to which she fell to the ground.
Surveillance cameras on the streets of the city filmed how the Mare shepherd dog breed first checked the condition of its owner, and then began to attract the attention of people to help her.
As a result, the pet managed to free itself from the leash and stop the truck. The driver helped the woman. More details on the video:
