Ancient sandstone engravings found in the Arabian desert depict dogs wearing leashes, according to a paper published Thursday in the Journal of Anthropological Archaeology and reported by David Grimm at Science.

Why it matters: It's difficult to date these carvings, but "based on the sequence of carving, the weathering of the rock, and the timing of switch to pastoralism" the pictures are likely 8,000-9,000 years old, writes Grimm, who notes that this would make them the oldest known depictions of dogs.
