There are numerous organizations that take stray or abandoned dogs and train them to become service dogs. This is a very noble thing to do because it benefits so many sides. It benefits the dog because it makes it more likely to find a very dedicated owner, and a caring forever home, and it benefits the owner even more, because the pooch helps them lead a normal daily life.
However, have you ever heard of service horses? Saratoga War Horse, a retirement home for former race horses, decided to put together its horses and army veterans to help them treat traumatic experiences, the so called PTSD. The veterans can’t take the horses home, but they can come spend time with them as much as they want, and for so many of them, it’s been a life saving experience.
