2 Pack Dog Whistle,to Stop Barking Neighbors Dog, Adjustable Ultrasonic Silent Dog Whistle, Professional Recall Dog Training

【Stop Dog Barking】: When your dog or a neighbor's dog won't stop barking, blow the dog whistle gently. The ultrasonic waves from the whistle will easily attract your dog's attention and stop him from barking. 【Adjusable Frequencies】: Different dogs will respond to different frequencies. Our dog training whistle has a nut and screw that adjusts the frequency when rotated. Please pay attention to how your dog responds to each setting until your dog shows the strongest response. 【Remote Command】: Ultrasonic waves can travel up to 1000 meters. After training, even if your dog is not in your field of vision, your dog will be able to perform the corresponding actions according to your whistle (sit, pat with paw, lie down, get up, heal). 【NOTE】: Please note that this dog training whistle will not make your dog understand your commands immediately. It will take several sessions before your dog understands your commands. Use the Reward-Positive-Behavior method to make your dog an obedient friend. Training is more effective when your dog is 3 to 7 months old.
