A dog rescued from the Los Angeles River during an unexpected, quick-moving storm on Friday remains unclaimed today by his owner.

The 18-pound Welch Corgi mixed breed -- dubbed "Lucky" by the firefighters who rescued him -- is about six years old, said Jan Selder, director of field operations for the Los Angeles Department of Animal Services. Subscribe to News Alerts and a Daily Email Newsletter for Hollywood Patch

He is being housed at an animal shelter and is no worse for wear for his ordeal. "He looks great," Selder said. "I visited him yesterday."

The dog was plucked from the water by a paramedic/firefighter who was lowered into the rain-swollen river near the Cahuenga Pass by a fire department helicopter at 3:45 p.m. Friday. Lucky had no microchip implanted, and bore no identifying tag, and no one has come forward to claim him, Selder said. If no owner claims him by Thursday morning, he will be put up for adoption.

Anyone interested in adopting him can call the Department of Animal Services at (888) 452-7381.
