The intelligence of dogs

The Intelligence of Dogs is a book on dog intelligence by Stanley Coren, a professor of canine psychology at the University of British Columbia in Vancouver. Published in 1994, the book explains Coren's theories about the differences in intelligence between different breeds of dogs. Coren published a second edition in 2006.

Coren defines three aspects of dog intelligence in the book: instinctive intelligence, adaptive intelligence, and working and obedience intelligence. Instinctive intelligence refers to a dog's ability to perform the tasks it was bred for, such as herding, pointing, fetching, guarding, or supplying companionship. Adaptive intelligence refers to a dog's ability to solve problems on its own. Working and obedience intelligence refers to a dog's ability to learn from humans.

Methods

The book's ranking focuses on working and obedience intelligence. Coren sent evaluation requests to American Kennel Club and Canadian Kennel Club obedience trial judges, asking them to rank breeds by performance, and received 199 responses, representing about 50 percent of obedience judges then working in North America. Assessments were limited to breeds receiving at least 100 judge responses. This methodology aimed to eliminate the excessive weight that might result from a simple tabulation of obedience degrees by breed. Its use of expert opinion followed precedent.

Coren found substantial agreement in the judges' rankings of working and obedience intelligence, with Border collies consistently named in the top ten and Afghan Hounds consistently named in the lowest. The highest ranked dogs in this category were Border collies, Poodles, German Shepherds, Golden Retrievers, and Doberman Pinschers.

Dogs that are not breeds recognized by the American Kennel Club or Canadian Kennel Club (such as the Jack Russell Terrier) were not included in Coren's rankings.

Evaluation

When Coren's list of breed intelligence first came out there was much media attention and commentary both pro and con. However over the years the ranking of breeds and the methodology used have come to be accepted as a valid description of the differences among dog breeds in terms of the trainability aspect of dog intelligence. In addition, measurements of canine intelligence using other methods have confirmed the general pattern of these rankings including a new study using owner ratings to rank dog trainability and intelligence. 79 ranks are given (plus 52 ties), a total of 131 breeds ranked:
