There are two parts of this story, both equally as amazing. One about a feral dog, who was considered too dangerous to ever be adopted, but defied the odds and became a rescuer himself.
Rex was taking a walk with his owner when they saw a tiny hummingbird lying on the ground covered in ants. The man thought the bird was dead and urged his dog to keep walking, but Rex wouldn’t leave the tiny body. Miraculously, the hummingbird was indeed alive, barely. They took her in and nursed her back to health and today she and her canine savior are inseparable friends.
