Sorry to break it to you, but your dog probably has no recollection of that fun game of fetch the two of you played yesterday. And that yummy treat you gave him just minutes ago? Even that has probably gone poof!
The truth is, a dog's memory just isn't very good. And a new study suggests that the same is true for 25 other animal species, from bees and birds to big mammals. Their recall of specific events disappears within minutes or even seconds.
