premise: Looking through a vehicle's windshield at a dog crossing the road. hypothesis: A dog is walking outside.
entailment: Because someone is looking through a vehicle's windshield at a dog crossing the road, it would make sense that the dog is walking outside.  Vehicles are normally in garages or outside.  If a dog was crossing the road, then it is implied that the dog is walking outside.  The dog must be walking or running to cross a road.  Roads are outside, so the dog must be outside.
