From the video description:
Our family dog was stolen from our front yard in Denver, CO. Her name is Zoe and she is the sweetest, most playful dog on the planet. She was outside by herself, but her Dad works from home with a window facing the front and the temperature was in the high 50s today. She is extremely loved and spoiled at home and her family desperately wants her back. Please keep an eye out for this person and this truck, and let us and the police know if you have any information about where she is. And please share this video so others who might know where she is can see it. Thank you.
