Tim McLarty said the burner was inadvertently left on low after the family cooked dinner around 6 p.m. March 5. McLarty said Hunter, a 3-month-old Husky mix, woke McLarty's wife, Jill, around midnight by whining constantly.
"Somehow the flame went out, but no one noticed the knob was still turned on," he said.
McLarty said his wife let Hunter outside, but he continued to whine when he re-entered the house.
"He was in the hallway almost doing circles and then he sat next to the stove and started crying," McLarty said. "My wife turned on the light and she saw not only was the stove turned on, but at that instant she smelled gas. We were in shock that it had been running for hours."
The family of five adopted Hunter about two weeks before the leak from the Michigan Humane Society at a Petco store in Sterling Heights. McLarty said the family nearly adopted Hunter's sibling, but the puppy won them over.
He said that may have been a life-saving decision.
"We were ... grateful more than you can imagine," he said.
