GRAND BAY, Ala. (WKRG) — The Mobile County Sheriff’s Office is conducting a criminal investigation after a person left a dog barely alive in a garbage bag on the side of the road.

The sheriff’s office is now offering a $2,500 reward for whoever provides information leading to the arrest of the person responsible for the dog found on Henderson Camp Road.

Saturday, a video was posted on Facebook by the original person who found the dog. In the video, the man said he didn’t know what to do.

Moments after posting, Brooke Whitehurst saw the video. As a dog foster mom, she immediately sprang into action, asking the volunteer company, Wags for Whiskers, if they could help fund medical expenses for the dog.

“Just pure God putting me in the right place at the right time,” Whitehurst said.

When Whitehurst gathered the dog, he had bloodshot eyes, manged skin from sitting in his own feces and a bullet through his head.

She took him to the Semmes Animal Hospital.

“That brain swelling was causing him to be immobile from the top half of his body,” Whitehurst said.

Whitehurst and her husband came up with the name Chance for the dog, saying he was given a second chance once he was found.

His injuries, however, were too extensive, and he passed away on Tuesday.

“Honestly, it’s not just about Chance; it’s about all dogs that are in this shape,” Whitehurst said.

Mobile County Sheriff Paul Burch said he hopes that he can help change animal cruelty laws, strengthening penalties in Alabama.

“Those types of people who can just harm an animal for no reason whatsoever wouldn’t hesitate to do that to a human being either,” Burch said.
