There’s a BBC article on whether animals are capable of imagination. It looks like they have limited powers of imagination, similar to small children. Most of the examples seem to be from other apes.
Also from the BBC is a piece on how dogs can understand situations from a human’s point of view.
Still on dogs, here’s an interview with a scientist who studies dog cognition. It covers the launch of his company to help people evaluate the intelligence of their dogs and, at the same time, benefit science. It’s also got a few questions on how smart dogs are, what people wrongly assume about dogs and a bit about the history of their domestication.
