premise: A brown and white dog is leaping over a log in a field while another dog follows behind it. hypothesis: A dog is chasing a neighbor's dog out of the territory of his big back yard.
neutral: Just because one dog follows another doesn't mean any chasing is going on, let alone into or out of any particular territory; a log in a field doesn't necessarily indicate a back yard; two dogs in a field don't indicate whether any neighbor's got anything to do with anything (or whether or not either dog belongs to anyone at all).
