A pedestrian who was trying to help a dog that appeared to have been hit by a vehicle was struck himself by a passing car Saturday night near Sebastopol.

The incident took place just past 8 p.m. on a dark stretch of Occidental Road, said CHP Sgt. Ross Ingels.

The victim, who is believed to live in the neighborhood, saw a dog that he thought had been struck by a vehicle just west of Piezzi Road.

The man was trying to wave down traffic when he was hit by an oncoming car, Ingels said.

The man was taken to Santa Rosa Memorial Hospital with head injuries. The motorist stopped and called 911.

The victim's name was not immediately available, nor the extent of his injuries, Ingels said. It appeared they were not life-threatening, though, he said.

No alcohol was involved, Ingels said. The motorist was interviewed and released.

"It's just really dark out there and he didn't see him," Ingels said.

The dog was not found.
