Research by the award-winning Stanley Coren (USA), Professor of Psychology at the University of British Columbia - and the polling of 200 professional dog obedience judges - has revealed that the most intelligent of all dog breeds is the border collie, followed by the poodle and German shepherd. At the bottom of the list is the Afghan hound. Dogs at the top end of Prof. Coren's scale proved particularly intelligent and even understand a "vocabulary" of 250 words - equivalent to a human child of two!
