Firefighters in Parkville, Maryland made one lucky dog extremely happy last week. The furry dog was trapped in a blazing apartment, fighting for his life. Luckily, rescuers were able to act fast, extinguish the flames, and get the scared dog back to safety. The pictures taken right after the dog was pulled out from the fire show the pup grinning, as if he was smiling to thank firefighters for saving his life. Well, the pup sure had good reason to smile. If it weren’t for those firefighters, things probably would have probably ended badly for the dog.
