see The Hound (short story), for the titular H.P. Lovecraft story

"It was the oddly conventionalised figure of a crouching winged hound, or sphinx with a semi-canine face, and was exquisitely carved in antique Oriental fashion from a small piece of green jade. The expression on its features was repellent in the extreme, savouring at once of death, bestiality, and malevolence...
...For crouched within that centuried coffin, embraced by a close-packed nightmare retinue of huge, sinewy, sleeping bats, was the bony thing my friend and I had robbed; not clean and placid as we had seen it then, but covered with caked blood and shreds of alien flesh and hair, and leering sentiently at me with phosphorescent sockets and sharp ensanguined fangs yawning twistedly in mockery of my inevitable doom. And when it gave from those grinning jaws a deep, sardonic bay as of some gigantic hound, and I saw that it held in its gory, filthy claw the lost and fateful amulet of green jade, I merely screamed and ran away idiotically, my screams soon dissolving into peals of hysterical laughter."
-H.P. Lovecraft, "The Hound"

Little is known about the being called the hound in the titular story by H.P. Lovecraft. It is not known whether the hound is one of a race of "hounds" or a unique mutation of another race.
