Lucky got lucky.
Greg Bowser found the 12-week-old lab mix puppy in an open shipping container in a rail yard after a co-worker told him he'd seen a dog limping around an industrial area in Hollywood, Florida.
Lucky had survived being hit by a freight train.
"It was about 8:30 at night, and I went over with a flashlight, and when I did find him he was pushed up inside this container. That's when I realized that his leg had been completely cut of," Bowser told WSVN.
Bowser immediately took Lucky to Hollywood Animal Hospital.
Dr. James Dee, a veterinarian at the animal hospital, and his team were determined to save the young pup. They performed multiple surgeries, including an amputation to his severely damaged, infected and irreparable left hind leg.
The vets believe Lucky will recover well, and will be able to adjust to walking and running on three legs.
"Fortunately, Mr. Bowser had it in his heart to pick him up and see that he could get some good care," said Dee.
The Bowsers have already covered $800 of Lucky's $2,800 medical bills. They're currently fundraising the additional funds while looking for a loving family that will take him in.
In the meantime, Lucky has moved in with the Bowsers.
"I got Lucky home and introduced him to our beagle and dachshund. He got along great with both of them. He can't have a regular bath yet because the wound can't get wet, so I put him in the bathtub and use a wet washcloth to wipe them down. He was really dirty, but let me wipe him down and never struggled or complained," Bowser wrote.
