We all love dogs, but do you ever feel yourself getting annoyed with their constant barking? It's time to try this Ultrasonic Dog Bark Control Deterrent and never worry about this again! How The Outdoor Bark Control Works When the outdoor bark control is within range of a barking dog, an internal microphone picks up the sound and the unit is automatically activated. The outdoor bark control emits an ultrasonic sound which can be heard by dogs but is silent to humans. This high pitched tone is completely safe for any dog's ears and will effectively deter barking. When the dog stops barking the ultrasonic sound also stops. The outdoor bark control has 3 range levels and a test mode. It is effective up to 50 feet. Tips: 1. The product automatically detects the sound of dog barking, so it should be placed as close as possible to the dog's barking sound. 2. The effective range of the product is based on the premise that there is no obstacle in the middle. Please reduce metal obstacles while using this product. And the effective range for each dog is different, you can select the effective range suitable for the dog by setting different modes. 3. This product is useful for most dogs, but not all dogs. We do not recommend it for use on dogs under 6 months and over 8 years old. It may not be effective for large dogs or dogs with hearing problems. It is not intended to provide protection against aggressive dogs.
