Experts have discovered a set of engravings in Saudi Arabia dating back at least 8,000 years.
According to a report published last month,, the engravings depict a hunter accompanied by 13 dogs, two of which appear to be on leashes attached to the man’s waist.
According to archaeologists the engravings are the earliest known depictions of dogs on leads and suggests that humans were training dogs to assist them with hunting thousands of years earlier than previously thought.
