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.

(The word deferent comes from the Greek fero  "to carry"and Latin ferro, ferre, meaning "to carry.") An eccentric deferent is slightly off-center from Earth.

Italian Spanish Portuguese and Maltese: from ferro 'iron' (from Latin ferrum) used as a nickname denoting someone who was strong or as a metonymic occupational name for someone who produced or worked iron.
