premise: A man is holding a very long leash attached to a very large dog who is smelling the grass.
hypothesis: A man is walking a brown dog
explanation_1: The dog doesn't have to be brown and could be another color or a mix.
explanation_2: Large dogs can be a color other than brown.
explanation_3: Just because a man is holding a very long leash attached to a very large dog who is smelling the grass, doesn't mean he is walking a brown dog.
