Ultrasonic Dog Trainer & Bark Deterrent – Rechargeable Handheld Device
Encourage better behaviour with this Ultrasonic Dog Trainer & Bark Deterrent, a compact handheld device designed for everyday dog training and bark management. It combines ultrasonic sound, an audible beep and a built-in LED flashlight, providing convenient training options without the need for a bark collar.
The device features three ultrasonic emitters for expanded coverage, with both a fixed 25 kHz frequency and a variable ultrasonic frequency mode. With a control range of up to 23 ft (7 m), it can be used at home, in the yard or while walking your dog.
The lightweight and portable design makes it easy to carry in a pocket, bag or hand. A built-in 1000 mAh rechargeable battery and USB Type-C charging provide convenient power for regular use.
For best results, use the device consistently alongside positive reinforcement and appropriate training techniques. Ultrasonic sound may not be equally effective for every dog, so monitor your dog's response during use.

What's Included
Safety & Responsible Use
- Ultrasonic sound may not work the same for every dog. Results depend on the individual dog and consistent training.
- Not recommended for puppies under 6 months, or for dogs that are elderly, unwell or hearing-impaired.
- Use short presses only — do not use it continuously or excessively. Stop if your dog shows signs of fear or distress.
- Do not point the device at people's ears, or use it near other pets (such as cats or rabbits) that may also hear it.
- This device is a training aid, not a protective tool — it is not guaranteed to stop an aggressive dog. Keep a safe distance and seek help if needed.
- For persistent barking or behaviour problems, consult a vet or a qualified dog trainer.
- Keep away from water and out of reach of children. Do not leave charging unattended.
