Rechargeable Ultrasonic dog trainer deterrent humane all breeds small dogs DESCRIPTION Our Ultrasonic dog trainer offers an alternative method to distract your dog and other dogs from barking, or any other unwanted behaviour. The device transmits an ultrasonic high pitched sound (115 dBA) that only dogs can hear which essentially distracts dogs, humanely.  The high pitched sound that is emitted has a strong, repelling effect to stop barking, digging, jumping etc from up to 10m away and is so simple to use. Rechargable with the included USB cable - no more swapping out batteries.    SAFETY It is extremely safe to use for both dogs and humans and is small enough to keep in your pocket as an ‘on the go’ training tool.  The sound is not audible to humans but works to ward off loud, repetitive and aggressive barking dogs as well as to effectively teach your dog to stay away from unwanted areas such as furniture or garden patches if you choose to use the device in this way. Protect your small children from barking dogs Avoiding unfriendly neighbourhood dogs as a walker, runner or cyclist Perfect for delivery and utility workers to keep a safe distance from barking dogs Stop your neighbour's dog from barking constantly  Package Included 1 x Ultrasonic device 1 x USB cable
