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.
