Dog, an animal frequently mentioned in Scripture. It was used by the Hebrews as a watch for their houses, Isa. 56:10, and for guarding their flocks. Job 30:1. Then also, as now, troops of hungry and semi-wild dogs used to wander about the fields and the streets of the cities, devouring dead bodies and other offal, 1 Kings 14:11; 21:19, 23; 22:38; Ps. 59:6, and thus became so savage and fierce and such objects of dislike that fierce and cruel enemies are poetically styled dogs in Ps. 22:16, 20. Moreover the dog being an unclean animal, Isa. 66:3, the epithets dog, dead dog, dog’s head, were used as terms of reproach or of humility in speaking of one’s self. 1 Sam. 24:14; 2 Sam. 3:8; 9:8; 16:9; 2 Kings 8:13.
