Homeless man Keith Walker is the hero to thank after his quick actions saved several lives.

Walker saw Atlanta animal shelter W-Underdogs catch fire after a fire engulfed its kitchen. He rushed inside to save several cats and dogs that were still trapped inside. Walker told CNN"I was nervous as hell, I'm not going to lie. I was really scared to go in there with all that smoke. But God put me there to save those animals. If you love a dog, you can love anyone in the world. My dog is my best friend, and I wouldn't be here without him, so I knew I had to save all those other dogs."

According to W-Underdogs founder Gracie Hamlin, the shelter was not completely destroyed, but the fire left it uninhabitable. Luckily, W-Underdogs was only a week away from moving into its new facility in Atlanta, where all the saved animals now reside. Hamlin shared, "I can't thank him enough for saving my animals. I'm still in disbelief, because I've been around a fire and I know how fast they flare up. He is my hero."
