BIG DEAL Ultrasonic Bark Control Device Anti Barking Devices Variable Frequency Hand held Stop Dog Barking Device Dog Barking Deterrent for Dog Behavior Training Dog Repellent Barking Control

How to train your naughty puppy? When the dog has bad behaviours,you can use our ultrasonic training device to improve it,simply press and hold for 10s towards him (within 16.4ft), or switch to Variable Frequency (“?”) when the dog doesn't respond to it. In order to achieve the desired results, once your dog accepts the ultrasonic bark controller correction and stops barking, you can give the pet appropriate rewards, such as snacks, petting, etc., to actively guide and strengthen the dog's memory. The dog will eventually learn to associate the barking with the ultrasound, forming a conditioned reflex and will stop barking this behavior. ?Tips: Consistent training and appropriate rewards are required to achieve the desired result.?
