Fire officials said that Environmental Services had removed the manhole cover to inspect storm drains when the unsuspecting pup fell.
Tess’ owners, Larry and Linda Beutler, described how Tess fell into the hole to KGW-TV.

"She just walked up expecting a treat and just went over the edge and disappeared," Larry Beutler said. "So that was quite a shock."
To reach Tess, a firefighter was lowered down into the manhole. The firefighter strapped Tess in a harness and a pulley system was used to hoist her back up to the street.

The rescue operation lasted about an hour, according to the station. Officials said Tess wasn’t hurt in the incident because a pile of leaves and debris at the bottom of the manhole cushioned her fall.

Last week, another pup was rescued off the coast of Long Beach, California, after beachgoers spotted the small dog stranded in the Pacific Ocean.
Chase McColl, a marine safety officer with the Long Beach Fire Department, jumped into action and set off on a paddleboard to rescue Tofu and safely reunited the dog with her owner.
"I just met the owner today for the first time and they're super thankful and happy we were able to save their pup and bring them back to him," McColl said during an interview on "America Reports."
