Train your pet to accompany you anywhere without a lead. The digital remote with LCD display screen is simple to use to train your dog better behaviour. The Remote Transmitter sends a signal activating your dog's Receiver Collar. The soft, stylish collar delivers a safe but annoying electrical stimulation. He'll quickly learn the association between his behaviour and your training; in no time, you'll have a better-behaved pet. The PetSafe® Little Dog Deluxe Remote Trainer has been proven safe, comfortable and effective for dogs 3.6kg - 18kg.
