Dog intelligence is the ability of a dog to learn, think, and solve problems. Dog trainers, owners, and researchers have as much difficulty agreeing on a method for testing canine intelligence as they do for human intelligence. One specific difficulty is confusing a breed's genetic characteristics and a dog's obedience training with intelligence.

Dogs are pack animals by nature and can understand social structure and obligations, and are capable of interacting with other members of the pack. Adult canines train their young by "correcting" them when they behave in an unacceptable manner (such as biting too hard or eating out of turn) and reward them for acceptable behavior, by playing with them, feeding them, or cleaning them.

They are also den animals. This means that they can easily learn behavior related to keeping the den clean (such as housebreaking) and relaxing in an enclosed area (such as a crate during travel or for training).

Some breeds have been selectively bred for hundreds or thousands of years for the quality of learning quickly. That quality has been downplayed for other breeds in favor of other characteristics like the ability to track or hunt game, or to fight other animals. The capacity to learn basic obedience and complicated behavior, however, is inherent in all dogs. Owners must simply be more patient with some breeds than with others.
