His story captured the hearts of thousands of our viewers a dog severely injured at the hands of his former owners.
Now Diesel is getting a new "leash" on life thanks to Detroit Dog Rescue. The 2-year-old pit bull is recovering after surgery after being abused severely.
It was originally thought that vets could remove a bullet from his nose - but it turns out the suspected former owner shot him in the head - and the bullet cannot be taken out.
"They had to wire his jaw because it busted his jaw," said Teresa Wright, Michigan Anti-Cruelty Society. "He's going to be okay, he's sweet as sweet could be."
Detroit Dog Rescue picked up Diesel Friday afternoon from the Michigan Anti-Cruelty Society. This after, a Good Samaritan Brianne Smith saw the former owner beating Diesel outside her job last Friday at the corner of Eight Mile and Schaeffer.
FOX 2: "Did you get a good look at the owner?
"Decently, but to be honest I was (highly) emotion(al) after seeing him kick the dog, slam his head in the door of the car. I freaked out."
When she started to call police, the man took off, but Diesel came back.
"A couple of hours later when I was told the dog was back and was severely bleeding, we found him running down this way," Smith said.
Smith wants to adopt Diesel, but there will have to be a long process.
"We're going to assess where Diesel is at," said Kristina Rinaldi, Detroit Dog Rescue. "Where that bullet is at, what he is going to need next."
"I think he's got a long road before we think of adoption just yet, we want to get him healthy, temperament tested like we do with all of our dogs, but it's a great day when rescues in Detroit can work together."
Diesel's road to recovery will now begin, but the person out there who abused him is still out there. DDR is offering a 2,500 reward leading to an arrest.
