WHY PET PARENTS CHOOSE IT
Quieter days.
No shock, no spray.
It works by association: an ultrasonic tone your dog hears (but you barely do) marks the moment of over-barking, so the behaviour fades with consistency.
◎
Three intensity levels
Start gentle and step up only if needed, matching sensitive and stubborn dogs alike.
⌁
USB-C rechargeable
A built-in 1200 mAh cell charges over the common USB-C cable — no disposable batteries.
◉
Made for outdoors
Rated for -20°C to 60°C so it keeps working through cold mornings and hot afternoons.
HOW IT WORKS
Consistency does the training — not force.
01
Charge over USB-C
Top up the 1200 mAh battery before first use.
02
Choose an intensity
Begin on the lowest of the three levels.
03
Trigger on over-barking
Activate the ultrasonic cue the instant nuisance barking starts.
04
Reward the quiet
Praise calm behaviour so your dog links quiet with good things.

QUESTIONS, ANSWERED
Frequently asked questions.
01Can I hear the ultrasonic tone?
Most adults cannot hear 25 kHz. Some children and young people with sensitive hearing may notice a faint sound.
02Is it safe and humane?
It uses sound only — no static shock and no spray. It interrupts the barking moment so your dog can learn; it does not cause pain.
03How do I charge it?
Over the common USB-C cable. The built-in 1200 mAh battery does not need replacing.
04Will it work in cold or hot weather?
It is rated for -20°C to 60°C, covering most outdoor conditions.
05My dog barks from anxiety — will this help?
No. Barking driven by fear, pain or separation anxiety needs its cause addressed first. Speak to a vet or behaviourist.
