St Louis firefighters helped a dog that had gotten its head stuck inside a pipe on Friday, April 20. Officials were not sure how or why the dog got its head stuck inside the pipe.A St. Louis police officer was on hand to capture the moment the dog was freed on video. In it, firefighters can be seen snipping the pipe while trying to wiggle the dog free. While responders were worried the dog would jump or run away, the dog was calm and sat as he was petted by the responders after he was freed from the pipe.
