premise: Two dogs are playing together.
hypothesis: Two mutts are chasing each other.
explanation_1: Dogs are not assumed to be mutts.  Playing together does not imply chasing each other.
explanation_2: Just because the dogs are playing together doesn't mean they are mutts or chasing each other.
explanation_3: Not all dogs are mutts and playing does not only mean chasing each other.
