A Florida dog grooming business opened its doors overnight to help take care of an abandoned dog in severe need.

Kari Falla, owner of BGE Grooming, said she knew immediately when she saw a Facebook post about the dog on a page for lost dogs that the pup needed urgent help.

“They said they found it on the side of the road and it almost got hit by a car,” Falla told InsidEdition.com. “They couldn’t keep it for the night and the woman was looking for someone who could.”

Falla knew that the dog was badly matted from the pictures and that it could be dangerous for its health, so she reached out to the woman who created the post. She said to bring the animal to her shop.

They showed up just an hour later and Falla performed an "emergency grooming" on the animal.

“They arrived at my shop at midnight and it took three hours to groom him. A normal groom only takes an hour-and-a-half,” Falla said. "When a dog is matted that badly, it can cause its blood flow to stop as well as bruising to the dog.”

Falla said the pup was matted so severely that it could not use the bathroom. It was also infested with fleas.

“I could tell he’d been that way for a few years from the pictures. You could tell it was extreme neglect,” Falla said. “I knew it was bad, but nothing prepared me for what I saw. It smelled like death and the dog could not walk. They had to carry it.”

Once the 4-year-old dog arrived, Falla shaved and bathed the animal, which was later determined to be deaf and blind.

“The dog was perfect for me when I was grooming him. It’s like he knew I was helping him,” Falla said. “Once we shaved him, he was wagging his tail and was so happy. I knew I did the right thing.”

Falla said the dog was the worst case she’d seen in her life.

“It made me cry,” she said.

The dog, which they named “Lucky,” was taken to the vet and neutered the next day.

He has since been placed in a foster home while he recovers, Falla said.

Officials are reportedly searching for the animal's original owner.
