From A Wiki of Ice and Fire
Hellhounds are creatures in some legends, presumably being supernatural canines.
Symeon Star-Eyes is said to have seen hellhounds fighting at the Nightfort. Hellhounds are among the stone gargoyles of Dragonstone.
A Clash of Kings
Tyrion Lannister thinks of Ser Gregor Clegane, Ser Amory Lorch, and Vargo Hoat as the hellhounds of his father, Lord Tywin Lannister.
