The SportDOG Brand FieldTrainer 425X and 425XS have been proven safe, comfortable, and effective for all dogs over 8 pounds. Consistent, correct use of this product allows you to reinforce commands and correct misbehavior from up to 500 yards. The Remote Transmitter sends a signal, activating the Collar Receiver to deliver a harmless stimulation. With proper training, a dog will learn to associate this signal with a command. Like all SportDOG products, this model features adjustable static stimulation levels so you can tailor the level to your dog’s temperament.
