A Remote Training Device is a tool used to train animals, particularly pets like dogs, from a distance. These devices often use sound, vibration, or mild electric stimulation to communicate commands or correct unwanted behaviors. They are designed to help pet owners reinforce training without being physically present, making it easier to manage pets in various environments. These devices typically come with a handheld remote control that allows the trainer to send signals to a collar worn by the animal. Many models are adjustable, offering different levels of stimulation to suit the needs of different animals. Popular brands include PetSafe and SportDOG.
