Negative punishment

Negative punishment means removing something the dog wants immediately after a behaviour, which makes that behaviour less likely to happen again. "Negative" refers to something being taken away, not to the method being harsh, and in practice this tends to be one of the gentler, more widely used tools in modern training.

A common example is ending a play session the moment a dog's teeth touch skin during rough play. The dog loses something they were enjoying, and over repeated instances, the biting during play reduces.

Negative punishment works well precisely because it doesn't require anything unpleasant to happen to the dog. Turning away from a jumping dog, pausing a game, or briefly withdrawing attention are all examples of removing something valued, in this case attention or play, rather than adding anything the dog dislikes.

This makes it a popular choice among trainers who prefer to avoid positive punishment altogether. The dog still learns that a behaviour has a cost, but the cost is the temporary loss of something good rather than an unpleasant experience.

Timing matters just as much here as with any other consequence. Removing attention a beat too late, after the dog has already stopped the unwanted behaviour, risks punishing something else entirely. It's also easy to remove something too briefly for the dog to actually notice the loss, which weakens the effect.
