A dog left behind after a family moves out of their Detroit home has a new lease of life.
It's a heartbreaking photo making the rounds on social media. It's hard to imagine that someone could just leave behind this beautiful, friendly dog.
But that's what happened to Boo.
Mike Diesel of Detroit Youth & Dog Rescue said, "It's absolutely heartbreaking for him. It's heartbreaking for anybody that sees it."
Boo was found, laying down alone outside on a mattress next to a pile of trash, waiting for his family to return for about a month.
Neighbors say he was left behind when his owners were evicted from their Northwest Detroit home.
"They came back one time, took the belongings that they chose to keep. Unfortunately, that wasn't Boo."
Luckily, neighbors fed Boo and tried to get the word out on social hoping someone would come to his rescue.
Mike spent more than 15 hours just to gain Boo's trust.
He said, "Getting to know my voice. Getting him to know that I wouldn't hurt him. Getting him to know he can trust humans again."
Mike brought the pit bull mix to Groesbeck Animal Hospital and gave him the name, based on markings on his left side.
"It appears to say 'Boo.' There is a 'B.' There is an 'O.' And there is another 'O.'"
Laura Owens is a veterinary technician of Groesbeck Animal Hospital. She is treating Boo.
"He is wonderful," she said. "You would think that he would be scared and fearful of people but he is not. He came in here wagging his tail."
Right now, Boo is heart worm positive but his overall health looks great.
"Dogs are the most loyal," Mike added. "If we can get humans to be anywhere close to that level of compassion then we would have a much better world."
Boo will be under vet care for the next 30 days, after that, the organization will be looking to find a foster home for Boo.
