The Intelligence of Dogs

According to S. Coren, author of "The Intelligence of Dogs", there are three types of dog intelligence:

Adaptive Intelligence (learning and problem-solving ability). This is specific to the individual animal and is measured by canine IQ tests.
Instinctive Intelligence. This is specific to the individual animal and is measured by canine IQ tests.
Working/Obedience Intelligence. This is breed dependent.
