Correction is a term used in certain segments of the dog training world. It commonly applies to jerking the dog’s leash (also called a “leash correction). Sometimes “correction” refers to other physical things people might do to a dog.

Trainers who use corrections do such things when a dog is performing an undesirable behavior. For example, they will perform a “leash correction” when a dog is pulling on the leash, is in the wrong position, or is not focused on the handler. The magnitude of a leash correction can range from a twitch of the leash to jerking hard enough to lift the dog partially off the ground or knock him off balance.
