A motorcyclist who dragged his dog by the neck along a road told stunned passersby it was "so he learns to return home"
The helpless pup, who is unable to keep up with the speeding bike, is dragged on its side along the gravel track as the grinning owner seems unfazed.
The dog looks lifeless and it is not known if it survived the ordeal.
Local media reported that the incident has been reported to police, who have started an investigation, after incensed locals gathered outside the town's police station.
The video was taken by stunned occupants of a minibus driving along the same Route 81 near Ibarreta, northern Argentina.
