Dog sniffs out grammar
A border collie takes command of sentence rules

COMMAND PERFORMANCE A border collie named Chaser participates in an experiment testing her ability to understand commands given before she can see any of the objects named in those directives. After hearing a four-word command, Chaser consistently turned around and carried the correct item from the head of the bed to the living room, where she placed it next the appropriate object.
