Use "wolf-dog" in a sentence
"At the man's heels trotted a dog, a big native husky, the proper wolf-dog, gray-coated and without any visible or temperamental difference from its brother, the wild wolf."
"And the wolf-dog, with ears flattened down and crouching, would slide silkily away, only to circle up to the foal from the other side and give cause to the mare for new alarm."
"And as the old hunting instincts had aroused that day in the wolf-dog, so in him recrudesced all the old hot desire of gold-hunting."
