K-II Enterprises Pet-Agree Ultrasonic Dog & Cat Trainer makes training your pet easy. A painless alternative to shock collars， chokers or physical force， this device allows you to reinforce your training efforts with a silent， humane， high-frequency sound that is audible to dogs and cats， but not to humans. The ultrasonic tone keeps the attention of your furry friend， much like your voice would， assuring that they understand the command. Just point the trainer at your dog or cat， give the verbal request and press the button for one or two seconds to ensure comprehensive understanding from your pet. This is a perfect device for any pet owner， groomer or kennel operator who needs help breaking a bad habit or teaching a new command.
