DOGGY INTELLIGENCE
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.

Certain breeds, like Border Collies, Poodles, Vizslas and Golden Retrievers, are generally easier to train than others. It is worth noting that these descriptions are relative to other dogs, not relative to the world at large. The ability to learn and obey commands is not the only possible measurement of intelligence.

DOGGY COMMUNICATION
There are a number of basic ways a dog can communicate. These are movements of the ears, eyes and eyebrows, mouth, head, tail, and entire body, as well as barks, growls, whines and whimpers, and howls.

Often undiscussed, some dogs may try to repeat human speech sounds, or are trained to. This kind of vocalization does not have a set meaning, and is unique to its situation. Recent examples have included a talking pug on the Late Show with David Letterman.

As humans migrated around the planet a variety of dog forms migrated with them. The agricultural revolution and subsequent urban revolution led to an increase in the dog population and a demand for specialisation. These circumstances would provide the opportunity for selective breeding to create specialized working dogs and pets.
