(1) “Electronic collar”: A corrective collar that administers electric shock when the owner presses a remote control. They are used to rapidly give a correction when a dog performs an undesirable behavior, and can be used as part of positive punishment or negative reinforcement. The latter is most commonly used for teaching recall. Many models of e-collar are able to alter the level of electrical stimulation given to the dog and also come with a beeping, and/or vibration function to create a conditioned emotional response and minimize use of the shock itself.
(2) “Elizabethan collar”: A plastic cone fitted around a dog’s neck after surgery to prevent him interfering with his wounds healing. Colloquially known as the “cone of shame”.
