A drawing by Konrad Lorenz showing facial expressions of a dog – a communication behavior. y-axis = fear, x-axis = aggression.

Dog intelligence is the ability of the dog to perceive information and retain it as knowledge in order to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. [4]

Coren's book presents a ranked list of breed intelligence, based on a survey of 208 dog obedience judges across North America. [10] When it was first published there was much media attention and commentary in terms of both pros [11] and cons.
