And no one cheered more loudly than the construction crew, who had, for months, been heartbroken eyewitnesses to the dog's plight.
"The only reason why the animal had food, water or shelter was because of the construction workers," Susan Turner of rescue organization Nadia's Hope Foundation tells The Dodo.
Indeed, the workers, haunted by Demo's plight, built him a shelter from brick and tarp. They laid cedar shavings on the ground. And even shared their lunches with Demo.
Since the story was first reported on The Dodo on Thursday, animal lovers around the world have rallied to save the dog. The chief of police woke up Friday morning to 450 emails.
For city councillor Jeff Miller, the story seemed so shocking, at first he didn't believe it was happening in his town. So he drove around late that night, trying to find Demo's pen.
And it turned out, "I live like nine-tenths of a mile from there."
"That's when it all kind of came into focus," he says. "And this morning, it all hit the fan."
Miller drove with the police chief to the house this morning. They persuaded the dog's owner to give him up. His owner was waffling right until the end.
"The truth is the gentleman who owned the house, he was an older gentleman, had tried to take care of him," Miller explains. "But it was his son's dog and his son was in prison."
