How Smart are Animals- Showed animals from a dog to an octopus displaying amazing intelligence to solve problems. The 1st one they showed was a dog who was able to retrieve 100's of uniquely named toys just by someone telling him to find it by name. They then mixed in a new toy the dog had never seen before or heard it's name. The dog was asked to find the toy it had never seen before and was able to figure out that the toy it had never seen before must be the one it was being asked to get.
