How it works
Three steps to a quieter home
No training experience needed. nexora gives you a simple, gentle way to teach your dog when to stop.
Press the ultrasonic button
A short tone that people can't hear breaks your dog's focus on barking within seconds.
Reward the quiet
Praise or treat the moment they stop. With repetition, quiet becomes the habit.
The science
A sound your dog hears. You don't.
Human hearing tops out around 20 kHz, while dogs can hear up to about 45 kHz. nexora works in the gap between, so the cue reaches your dog without bothering anyone else.

FAQ
Questions, answered
Is it safe for my dog?
Yes. nexora uses high-frequency sound to get your dog's attention and interrupt barking, with no contact, no shocks and no pain. It's a training cue, not a punishment. Use short bursts and avoid pointing it at your dog's ears from very close range.
Can people hear it?
The ultrasonic tone sits above the range of human hearing, so you and your neighbors won't hear it. The separate alert button makes an audible sound when you want one.
Does it work for every dog?
It suits most adult dogs of all sizes. We don't recommend it for puppies under 6 months, senior dogs, pregnant dogs, or dogs with hearing loss.
How fast will I see results?
Many dogs pause at the very first cue, but lasting change takes consistency. Use it the moment barking starts, reward the quiet right away, and repeat every day.
How do I charge it?
Use the included USB cable (5V / 1A). The 800mAh battery level is always shown on the display.
How long does shipping take?
Standard shipping is free to every US address and arrives in 3–5 business days. Express shipping (1–2 business days) is available at checkout.
