When a 4-year-old goes missing it's crucial to find the child within the first 48 hours, because they know from experience that a young child would have a hard time surviving outdoors that long without help.
So when little Karina Chikitova wandered into a forest in Siberia and got lost her family panicked, and when the hundreds of people searching for her had yet to locate her a week later they began to give up hope.
But Karina was lucky because her dog Kyrachaan had gone with her, and Kyrachaan was able to help Karina stay warm at night and defend her from wolves and bears in the forest until help arrived.
Eleven days after her disappearance Kyrachaan showed up in the village and pointed rescuers in the right direction, and four miles from the village in the tall grass they found Karina.
Karina had survived by eating berries, and had a few scrapes and bug bites but no major injuries, and the first thing she said when she saw Kyrachaan again- "Why did you leave me?"
