Dog is stuck on railroad tracks for 2 days. Brother keeps her warm and fed until help arrives..

The bond between man and dog is known to be strong and inseparable, but what of the bond between dog and dog? More specifically, a brother and sister dog?  The footage below shows the unbreakable strength of that bond, and the lengths these siblings would go to for one another.
In the video, the female dog is stuck to the railroad – a live railroad with trains still running over it. She was stuck for two whole days, but her brother refused to leave her side.

In one startling clip, you can see a train actually run over the dogs, but the brother protectively lies with his sister and they survive.

 He kept her warm during the two days and brought her food, and his efforts kept them alive until the pair could be rescued.
