A Remote Training Collar is a device used to assist in training dogs by delivering a mild electric stimulation, sound, or vibration. It typically consists of a collar worn by the dog and a remote control held by the trainer. The collar can help reinforce commands and correct unwanted behaviors from a distance, making it useful for training in open areas. These collars are adjustable, allowing trainers to set the intensity of the stimulation based on the dog's size and temperament. Many models also include features like a tone or vibration mode, providing alternative training methods without using electric stimulation.
