Truly decent point that sometimes these things happen unexpectedly and people can't get home to free them.most times when a fire breaks out people are at work and unable to get back home to set their animals free.once the road is closed and evacuation orders are issued you are not getting back home.animals in a barn will usually just stay in the barn even if the door is open.that is their home.horses in a field will figure out how to bugger off though and come back home when it is all said and done
There' This Korean war movie in one scene where the brothers realize they may not go back home for a very long time (they thought they would be gone temporary) he says how he should have untied the dog. That scene makes me so furious that i cant watch that movie ever again.
