This training system uses Ultrasonic tone, activated by the owner, to let the dog know what is acceptable behaviour. When the system emits the ultrasonic sound, or the 'negative' tone, the dog will understand that he needs to stop whatever he is doing - his behaviour is unacceptable.
The system also has a 'positive' tone so you can let him know when he is being good too! The two-button battery operated system works up to 9 metres away and requires no receiver collar.
