A Russian Uber driver working illegally in the US was caught on camera head-butting a South Carolina CEO as he held his service dog, leaving the knocked-out rider with a brain injury, according to the victim and a new lawsuit.

Charleston-based CEO Bryan Kobel, 45, canceled a ride home from a French restaurant, Maison, in April because the driver refused to take his service dog, Kobel told The Post on Thursday.

Disturbing surveillance footage shows the driver — identified as Vadim Uliumdzhiev, 42 — suddenly marching over and knocking out Kobel as he holds his 17-pound golden doodle in the parking lot.

“The next thing I know, I’m waking up in a hospital bed with seven staples in my head and four stitches,” Kobel said. “It’s been a brutal experience to this day.”
