A woman frantically chased after her pet dog that ran across a road in Denver, Colorado.

The dashcam footage, filmed on September 30, shows a large dog jog onto the road in front of cars before quickly sprinting off.

After a few moments, a woman can be heard screaming and sprinting across the road after her dog.

The filmer told Newsflare: "These are some of the things you run into while driving for Rideshare. I was about 10 feet away from hitting her dog but slammed my breaks before anything could happen then looked to my right and saw her running after her pet."
