At the end of the hunting season in Spain, the galgos deemed worthless or too costly to maintain are destroyed in a variety of inhumane ways  including being hanged, dumped into abandoned wells, shot, and even burned to death.

The galgo does not need much exercise. Three walks of 20 minutes a day is usually enough. Despite being the athletes of the canine world, galgos are not very active dogs. Obviously it depends a lot on the age, a young galgo less than two years old has more need to run than an older one.

Silent Hill 3 Is One Of The Most Disturbing Horror Games Of All Time.

Long answer: I think it's best to start with the series' crown jewel, Silent Hill 2. If you're going to play 3, be sure to get a PS1 emulator and finish 1 first because 3 bases heavily on the first game's storyline (while 2 has its own independent story completely unrelated to any other SH title).
