A wealth of clicker training videos

The way clicker training works is that the dog learns a click is a good thing (treat association). Clickers are then used to mark the exact instant of good behavior, making it much easier for the dog to figure out which behaviors to replicate. This is especially effective in dogs with a high drive to please; companion dogs and hunters meant to work close in concert with their people (like gun dogs), and shepherds in the collie family or with similar function.

Below is a particularly good example of clicker training. It also illustrates pretty well a dog's ability to experiment for itself to figure out exactly what its people are trying to get it to do.
