An off-duty nurse treated the woman and an air ambulance was sent to the scene before she was taken to Queen Elizabeth Hospital in Birmingham.
WATCH: Footage shows moment woman and pet dog are mowed down
Warning: Contains distressing footage
CCTV footage has now been released showing the moment the crash happened just before 5pm on July 22.
In the video, the Clio can be seen swerving across the road before ploughing straight into the woman and her dog.
A black Vauxhall Astra travelling in front of the Clio brakes suddenly as the woman is hit before people from both cars run away from the scene carrying bags.
Two men and a woman emerge from the roadside where the Clio was dumped with front-end damage as two men get out of the passenger-side of the Astra.
Tyre marks are also clearly visible on the road where the Clio swerved.
West Midlands Police has released the footage in a bid to track down those involved, with no arrests made so far.
A spokesman from West Midlands Police said: "The crystal-clear CCTV footage shows a number of people running away from the scene.
"We are appealing to trace them, and need anyone with information to get in touch.
"We are also trying to find the black Astra that stops further down the road.
"We believe the two cars were travelling together and the people are probably friends with each other."
A West Midlands Ambulance Service spokesman said: "An off-duty nurse was on scene administering first aid to the pedestrian, a woman, who had been involved in a collision with a car.
"The woman suffered serious injuries and, once treated and stabilised on scene by ambulance staff, she was taken by land ambulance on blue lights to Queen Elizabeth Hospital Birmingham for further trauma treatment.”
Anyone with information is urged to call West Midlands Police on 101, quoting log number 3677 of July 22.
