This is a handheld device rather than anything the dog wears, which matters. Nothing is strapped to your dog and nothing fires automatically. You press a button, a tone sounds that most dogs find irritating, and the barking usually stops long enough for you to redirect the behaviour. Used sparingly and paired with a reward for quiet, it is an interruption tool. Used constantly, it stops working and simply stresses the dog.
Key Benefits
- Nothing is worn by the dog – you control every activation
- Inaudible to most adults, so it will not disturb the household
- Rechargeable, so no awkward battery sizes to keep in stock
- Small enough for a coat pocket on walks
Best For
- Interrupting a barking habit while you train an alternative
- Owners who have ruled out bark collars on welfare grounds
- Walkers who want a deterrent for loose dogs approaching
How It Works
Pressing the button emits a tone in the 20 to 25 kHz range. Dogs hear well above the human ceiling of roughly 20 kHz, so the sound is obvious to them and silent to you. The interruption gives you a window to ask for a different behaviour and reward it.
Pros and Cons
Pros: Non-contact, entirely under your control, and far less aversive than a shock collar. Very well rated by buyers.
Cons: Effectiveness varies a lot between dogs – some ignore it completely. It also affects every dog in range, not just yours.
Things to Consider
- This interrupts barking; it does not teach anything on its own – always pair it with rewarding the quiet that follows
- It will affect neighbouring dogs within range too
- Some dogs are unbothered by ultrasound, so treat this as worth trying rather than guaranteed
- Prices, availability and shipping times are set by the AliExpress seller and can change
