The Great Howl

'' "The stars seemed to whirl above him, breaking and reforming into the shapes of running dogs. Not just the stars, though: As if imprinted on the inside of his eyes he saw other dogs, shadow-dogs, flickering across his mind. The ghostly silhouette of a great hound raced between the slender pine trunks of a huge forest; another tumbled through a surging river, but not drowning or fight: It was part of the torrent, swift and joyful. Clouds drifted across a bright sky, and between them leaped slender, ferocious Warrior-Dogs, springing from cloud to cloud, their leader a bright slash of light that hurt the eyes." ''—Lucky's thoughts of the Great Howl

The Great Howl is a howl that Alpha's Pack howl every night to. The sing to the Spirit Dogs.

Quotes
"In his very bones, Lucky was aware that the dogs around him were howling to particular Spirit Dogs. There was a high, silvery note to Moon's howling that her pups did their tiny best to echo; Lucky wondered if she was crying out only ''to the Moon-Dog. Dart, the brown-and-white patrol dog, let out a cry to the Sky-Dogs, so fierce and clear that it somehow seemed to echo as far as the horizon. Fiery's deep rumbling howl was as rich as rocks and soil; and thought Mulch's cry was thinner, it too was filled with love of the landscape. The two of them were calling, each in his own way, to the Earth-Dog." ''—Narrator
