Not galgos but their British cousins greyhounds.  British greyhounds (including Ireland) also have a hellish life.  Greyhound racing is not a sport yet the Greyhound Racing Board of Great Britian still insists there is no cruelty involved.  Many unwanted greyhounds end up shipped to China where their hellish life gets even worse.  And hundreds end up in the Chinese meat market.
