www.havahartwireless.com/store/dog-trainers/5150g -- Does your dog misbehave at home by barking excessively, jumping on furniture or chewing? Are you interested in an easy, yet effective, solution to stop dog barking and misbehavior? The Havahart® Ultrasonic Basic Trainer can correct these actions by emitting a high-frequency sound that only your dog can hear. While the sound can't be heard by humans, your dog will be distracted by the frequency and stop the misbehavior. The tone can be adjusted to five different frequencies, depending on your dog's hearing sensitivity. The Ultrasonic Basic Trainer operates under two modes: Manual and Automatic. In Manual mode, simply press the Correction button on the remote whenever your dog commits an unwanted action. In Automatic mode, the Trainer will respond to barks and immediately emit the ultrasonic sound to stop dog barking. The Trainer can recognize barking sounds from up to 25 feet away. This Trainer also includes a safety feature when in Automatic mode, whereby it will time-out for five minutes if it is triggered more than six times within one minute. In addition, the Trainer will go into sleep mode when your dog does not bark, in order to conserve Battery power. This video explains how the Ultrasonic Basic Trainer works and how to train your dog correctly to respond to these tones. You will learn the basic functionality of the device and how to test the ultrasonic frequency to which your dog responds. The Trainer will default to the highest frequency, but it is recommended that you test your dog every few weeks to identify the most effective sound frequency to train and control your dog. Ultrasonic training devices are effective for about two-thirds of dogs, but some will not respond to the ultrasonic tone. If your dog is not distracted by the tone, you may need to try Dog Training Collars or alternate dog training systems. Havahart® Wireless also offers a Remote Trainer with a Bark Collar that may work better for your dog.
