reefraff, the story is from Spain, so maybe look into that? Didn't find too much else myself.
Zain, dogs are not wild animals where you can go buy a permit to hunt. They do not need their numbers checked in the wild. You can eat deer, but no one eats dog. No one owns a deer as a family pet. After a long day of work or whatever, a deer isn't excited to see you nor does it come over and lay it's head in your lap. You also agrue, the dog was his property, so this guy should get at least the equvilent of grand theft.
