When one of the brave dogs was hit by a fast-moving car while they were trying to cross the road the other members of the pack faced down danger to try and help their friend.
Instead of fleeing the animals ran to the injured dog’s aid after hearing its pained yelps, eyewitnesses revealed.
The upsetting video filmed by a resident of the city of Lanzhou show cars swerving to dodge the group of small dogs.
While they stood guard over their friend one of the strays is seen nuzzling at his friend to try and get a response.
The devastated hounds did not appear to understand their friend had died from his injuries as they waited for him to get back up, those at the scene reported.
It is claimed the callous driver did not even bother to stop to see if the dog had died.
The determined dogs did not leave the road as they were passed by car after car.
The clip spread quickly over Chinese social media and earned a slew of emotional comments.
One Weibo user said: “If only humans could be more like these dogs.”
The dogs did not leave their friend’s side until a resident moved its body to the side of the road.
The sad news comes amid calls for UK animal rights campaigners to ban shock collars.
The British Veterinary Association welcomed Edinburgh’s movement, declaring it a win for animal welfare.
Its president John Fishwick said: “With effective bans on the use of these devices in Wales and Scotland, we want to see action taken in England and Northern Ireland, including a UK-wide ban on their sale and import.
“Anyone in need of advice on dealing with pet behaviour issues should always speak to their vet to get advice on how to do it positively and humanely.”
The Kennel Club, Dogs Trust and Blue Cross have all been ardent campaigners against the devices that use aversive training techniques for animals with behavioural problems, pointing to research that says they are harmful.
