Sadistic videos posted online this year showing a man abusing a toy poodle have sparked revulsion among some viewers and calls by activists for changes to the law.

The seven videos show an unidentified man beating the dog, kicking it, dropping it on the floor and hurling it against furniture.

The first video was entitled "Abused dog." All appeared to feature a Japanese-speaking individual. They were uploaded to YouTube over a roughly two-week period starting in late January.
