If you ever worked with rescue dogs, then you will know that they are doing hard work. Searching for survivors after disasters like 9/11, that’s what they are trained for. Their goal is to find as many as possible, it’s a race against time. Then, when they can’t find any more survivors, that’s when they continue to search for the remains of victims. It’s hard on them and on their handlers and owners, you can see it in their eyes.
