[Update 2:49 p.m. ET] The mud-caked dog of a Canadian family has been found in a sinkhole that swallowed their home, but searchers have found no signs of the couple and their two daughters, ages 9 and 11, CNN affiliate CBC reported Tuesday afternoon.

[Posted 11:07 a.m. ET] A Quebec family of four was missing Tuesday after a massive sinkhole swallowed their home, according to reports from CNN affiliates.

Authorities said the home fell 30 feet into the hole when it opened around 9:30 p.m. Monday. A couple in their 40s and two children, ages 9 and 11, were believed to be inside, according to a report by CNN affiliate CBC news.

The couple’s vehicles were seen outside the house and efforts to reach them by cell phone were unsuccessful, authorities told the CBC.

"We tried to reach them by phone, because the father always wears his cellphone on him," Quebec Provincial Police Sgt. Ronald McKinnis told CBC. "The firefighters heard the cellphone, but they weren't able to [locate] it."

The hole was about 500 yards long and forced the evacuation of five other homes in the town of Saint-Jude, in a rural area near the Yamaska River about 40 miles northeast of Montreal, CNN affiliate CTV reported.

McKinnis told the CBC that the hole was first reported by a truck driver whose rig fell into it Monday night. He suffered only minor injuries, McKinnis said.

Search-and-rescue dogs were being called in to help the search, according to a report in the Montreal Gazette, and a helicopter was circling the area looking for signs of movement.
