UK guide dog charity seeks brainy puppies to help breed problem-solvers

Cognition project for eight-week-olds consists of series of tasks, including one that's unsolvable

Researchers are hoping to unleash a generation of smarter guide dogs by studying the cognitive behaviour of puppies and finding out who the clever boys and girls really are.

Guide Dogs, the sight loss charity, will analyse the responses of eight-week-old puppies to see which ones best handle surprises, how they interact with human voices and how they react to difficult and sometimes impossible problems.
