Emily Klehm, CEO of the South Suburban Humane Society, told Newsweek that while they rescue many dogs, Pumpkin’s was an “extreme case” that left them speechless. “He was severely emaciated and unable to walk,” she said.

Photos show how unbelievably thin the dog was — it’s a miracle he survived at all.

Vets administered fluids and shaved his matted fur. Despite the rough start, he started to perk up and went into foster care with one of the shelter employees.

“Thankfully, we got him into foster care, where he is starting to improve and stand on his own again,” the shelter wrote on Facebook. “His journey is still long, but we are incredibly proud of him so far.”

Updates from the shelter show the remarkable improvement Pumpkin has made in just a short time. While he was unable to stand when they first found him, he can now walk around the yard on his own, wagging his tail.

“This little man is so strong and getting better every single day,” the shelter wrote.

Though he’s still visibly thin, he has been slowly regaining weight. “This little man is progressing, and we cannot wait to see how much more he continues to improve!” South Suburban Humane Society wrote.

Pumpkin’s backstory is still unclear, but the shelter says he will be placed up for adoption once he gets medical clearance.

“Pumpkin will need a home that understands that he was severely neglected,” Klehm told Newsweek. “He doesn’t know how to be a dog, so everything from leash walking to toys are all new experiences for him. An experienced dog family would be best.”

In the meantime, he’s doing well and loves his foster home.

It’s heartbreaking that Pumpkin was neglected for so long, but we’re so glad he’s doing well and regaining weight — we hope he finds a forever home soon when he’s ready!
