"Honestly, I was skeptical. After two walks, my Border Collie who used to bark at every dog we passed just... stopped. She freezes the second she hears it. Three weeks in and it's still working."

No shock. No collar. Just sound your ears can't hear.
The device emits ultrasonic sound between 20 and 30 kHz. Completely silent to humans, but instantly picked up by dogs. When your dog barks, they hear a sharp, uncomfortable sound. Not painful. Not traumatic. Just disruptive enough to interrupt the behavior and redirect their attention back to you. With repetition, they associate barking with that sensation and stop on their own. It's sound conditioning, not punishment.
Everything it does, and how it does it
One button, three frequencies, 50 feet of range. No complicated setup. No app. No collar to adjust. Take it out of the box, press the button, and it works.
🔊
3 ultrasonic modes
Fixed 25 kHz or dynamic 20-30 kHz modes. Choose based on your dog's size and temperament. Small dogs often respond best to Mode 3, larger breeds to Mode 1.
📡
50-foot range
Effective indoors and outdoors. Works on your neighbor's dog from your yard, or on a dog you encounter on the other side of a parking lot during a walk.
🔦
Built-in LED flashlight
Useful for evening or early morning walks. Light your path without needing a second accessory.
⚡
USB-C rechargeable
Battery included. Charges with any USB-C cable. Slim and compact, it fits in a jacket pocket or purse without adding bulk.
Why this device and not a bark collar?
Bark collars only work on your dog, require fitting, and can stress your pet out. This device works with no contact, at a distance, on any dog within 50 feet, including your neighbor's dog.

In your pocket on walks, on a shelf at home
Compact and lightweight, it fits in any pocket. On walks, press the button the moment your dog starts barking at another animal or passerby. At home, place it facing the spot where your dog tends to bark most, whether that's a window, the front door, or a fence. The 50-foot range covers most everyday situations, including a neighbor's dog barking in the next yard.
Your questions, answered
Everything you need to know before ordering.
How does it actually work?
How does it actually work?
The device emits ultrasonic sound between 20 and 30 kHz when you press the button. Inaudible to humans, but clearly perceived by dogs. The sound is too uncomfortable to ignore, so it interrupts the bark and shifts the dog's attention. With repeated use, the dog learns to associate barking with that sensation and stops faster each time. This is sound conditioning, not pain.
Does it work on all dogs?
Does it work on all dogs?
For the vast majority of dogs, yes. Some particularly stubborn breeds like beagles, or dogs with hearing issues, may be less responsive. We also don't recommend using it on puppies under 6 months or senior dogs over 8 years old. If your dog shows no response after two weeks of consistent use, we'll give you a full refund.
Can humans hear the ultrasound?
Can humans hear the ultrasound?
Adults cannot. However, some teenagers and young children may be able to perceive the higher frequencies. If you have children under 15 in your home, use the device outdoors or away from rooms where they are present.
Which mode should I use for my dog?
Which mode should I use for my dog?
Mode 1 (dynamic 20-30 kHz): recommended for large or very active dogs. Mode 2 (fixed 25 kHz): for calm or medium-sized dogs. Mode 3 (fixed 30 kHz): best for small dogs. If a mode shows no result after a few uses, move on to the next one.
Can it work on my neighbor's dog?
Can it work on my neighbor's dog?
Yes, and that's one of the most common reasons people buy it. From your backyard or window, point the device toward the source of the barking. The 50-foot range covers most typical situations between neighboring properties. Many customers report using it successfully on dogs they encounter on the other side of a parking lot during walks.
How long does the battery last and how do I recharge it?
How long does the battery last and how do I recharge it?
The device recharges via the included USB-C cable. A full charge provides several weeks of use at a few sessions per week. Important: make sure the device is fully charged before use. A low battery produces a signal too weak to be effective.
Try it for 30 days. If it doesn't work on your dog, we'll refund you completely.
Most dogs respond on the first or second use. On walks, at home, or against a neighbor's barking dog: one button, a 50-foot range, zero contact with the animal. Order today with zero risk. If your dog doesn't respond after two weeks, we'll refund every cent.

Honestly I was skeptical. After two walks, my Border Collie who used to bark at every single dog we passed just stopped. She freezes the second she hears it. Three weeks in and it's still working.

My neighbor's dog barked literally all day long. I placed this on my deck pointing toward his yard. Within a week the difference was noticeable. My neighbor actually asked me what I did.

Small enough to slip into my jacket pocket. On walks I hit the button the moment my dog starts barking at someone. Two or three times and he settled right down. Never leaving home without it.

My husband uses it for the neighborhood dogs and it genuinely works. We can finally open the windows in the morning without being woken up by barking from next door.

It works. I tried everything before this. This is the first solution that gave me lasting results with my dog. Easy to recharge, discreet, and actually effective.

Used it in seconds during an encounter with an aggressive dog on our walk. The dog calmed down immediately. The flashlight is a nice bonus for late evening walks. Really solid product.

My golden retriever used to bark every time the doorbell rang. After two weeks of consistent use, he's almost completely stopped. I didn't expect results that fast.

Easy to recharge, low profile in my hand. The three modes really do make a difference. Mode 1 works best on my lab, Mode 3 on my mother-in-law's small dog. Well thought out.

I tested it from my backyard on the dog across the street that barked every morning at 6am. He stopped within three days. I genuinely did not think it could work at that distance.

Good product overall. Didn't click right away with my beagle but after sticking with Mode 1 for a few days, the barking dropped a lot. Just takes a little patience with stubborn breeds.
