A command is a simple word or expression that the dog is trained to understand. It generally tells the dog to perform a specific action.
A cue is more subtle. It is a prompt, hint or suggestion that affects the dogs behavior in a given situation. Pointing, looking at something or even a sound can be interpreted by the dog as a cue from the owner. A cue is a signal to which the dog interprets in his or her own way. Dogs sometimes communicates to the owner through verbal cues such as wimpering, wagging its tail, and scratching.
Dogs communicate in many ways with each other, using verbal cues, body language and facial expressions. They also try to communicate with humans using these methods. Humans, of course, communicate with dogs with commands and phrases. Dogs can learn hundreds of human sounds but they can't string them together.
Dogs turn down extra food if a human provides the right cues
Dogs can be manipulated to choose against their preference by human cues, opting to turn down extra food in order to follow the human's choice, according to results published Apr. 25 in the open access journal PLoS ONE. The work was led by Sarah Marshall-Pescini of the University of Milan.
