We'd tried yelling, a basic whistle — nothing worked. Within three days of mounting SonicHush near the back fence, our retriever went from barking at every car to near-silence. My neighbor texted me: 'What changed?' Peace at 5am, finally.

  • Choose your mode: Rotate the dial to select 15 KHz, 20 KHz, or sweep frequency — sweep cycles continuously so your dog never adapts to a single predictable tone.
  • Activate near your dog: Point SonicHush toward your dog the moment barking starts. The ultrasonic signal reaches their ears instantly, interrupting the bark cycle without any physical contact.
  • Repeat for lasting results: Consistent use pairs the sound with silence, building new behavior patterns. Most owners report 60-80% fewer barking incidents within the first 7-14 days.
  • SonicHush Anti-Barking Device (1x)
  • Mounting bracket for fence or wall use
  • USB-C charging cable
  • Protective packaging box

Why Dogs Stop Barking and Stay Quiet

Adaptive Frequencies Beat Habituation

Single-tone devices stop working in days — dogs tune them out. SonicHush sweeps up to 30 KHz so every correction stays novel and effective.

Three Adjustable Training Modes

SonicHush's three modes match any dog's temperament. Pair manual activation with a 'quiet' command and your dog learns the association faster.

SonicHush

Charges Fully in 40 Minutes

SonicHush charges fully in 40 minutes and runs 3-4 weeks between top-ups. Always ready for the 5am neighbor bark or an evening walk.

Mount It or Take It Anywhere

Mount SonicHush on a fence post for the neighbor's dog, grab it for walks, or set it by the door — up to 50 feet of reach, one device.

I take SonicHush on every evening walk now. The moment another dog appears across the street, one activation keeps my shepherd focused and quiet. The fast USB-C charge means it's always ready to go — no excuses not to bring it.

Daniel K.· Verified Buyer

Bought SonicHush expecting nothing. Mounted it on the fence post and within four days the nightly barking that had gone on for months just stopped. I'd catch a jar full of this quiet.

Frequently Asked Questions

+156 expertsreviewed it

Yes — position SonicHush elevated and aimed toward the source, within 50 feet of open line-of-sight. Hundreds of users report quieting neighbor dogs across typical fences. Results through solid walls are more limited, so placement is key.

That's the problem with single-tone devices — dogs tune them out in days. SonicHush sweeps 15-30 KHz continuously so corrections stay unpredictable. Users report results past the 1-2 week window where fixed-frequency devices fail.

SonicHush charges fully via USB-C in just 40 minutes and holds its charge for up to 3-4 weeks of typical daily use before needing a top-up. That covers weeks of morning walk corrections and overnight yard duty without hunting for a cable.

Yes. Large breeds respond to the high-intensity mode; puppies and small breeds do best on the lowest setting. Introduce any aversion tool gradually with dogs under 6 months.

Best results with clear line-of-sight up to 50 feet — position SonicHush higher and aim directly at the dog. Wood fences allow partial signal; solid walls reduce range. Fence-post or window ledge placement covers most neighbor scenarios.

Cats rarely react to these frequencies — most cat owners report no disturbance. Birds and small caged animals are more sensitive, so avoid aiming the device toward them. Generally safe in mixed-pet households.

For neighbor dogs: mount on a fence post within 50 feet, aimed at the source. For door triggers: position at dog head-height. On walks: hold and point directly. Clear line-of-sight always outperforms obstructed placement.

Collars often cause dogs to switch to whining once they adapt — and affect every dog in the home, not just the barker. SonicHush uses sound only: no contact, no refills. For neighbor dogs, a collar isn't even an option.
