Which of these dogs is a sighthound breed?

When I was in my teens I saw this huge dog looked like a pony walking towards me on its own it belonged I found out later to the local pub owner it was so friendly but the sheer size at first scared the life out of me that was my first encounter with an Irish wolfhound.

I live in Ireland and my brother in law occasionally breeds Irish wolfhounds, they are so sweet and goofy, they love to cuddle. If you are not used to these dogs the mere sight of them will scare you but they will quickly win you over with their sweet and lovely way.

Player #28521499, basically it hunts with sight instead of scent, like bloodhounds

I have a miniature wolfhound; she's one of the best nature dogs I've had.

They were allso used in combat to knock down solders warriors on horse back in ancient times.
