Drowning puppies is usual practice among older European village people.. they just cant take care of them, so they drown them but they do that immediatelly after they are born. I dont really like that, but its not unusual and it has nothing to do with animal hatred or something, its just an old habit of animal reproduction control. I find the video part much more shocking, as it shows that they have fun doing that.
The question is, do you also get so upset when they poison rats or shoot crows because of over reproduction?
