As a result of domestication, dogs are genetically predisposed to be more attentive to human social cues. This study investigates the influence of dog-directed speech (DDS) from humans on the basic quantity discrimination abilities of dogs in a food choice task. Forty two pet dogs were tested in four different conditions. Two plates with varying amounts of food were presented to the subject, ‘choosing’ a plate by eating from it. Experimental conditions sought to seek the influence of DDS from humans on dog decision-making in addition to measuring the influence of DDS and quantity discrimination alone.
