Ultrasonic anti barking devices do work
If you have been struggling with a noisy dog. Whether it is your own or a neighbour’s, you are probably wondering, Do anti-barking devices really work? The short answer is yes. Ultrasonic anti-barking devices can be highly effective when used correctly, in the right situation, and combined with proper training techniques.
At DAZER Australia, we have helped thousands of dog owners and neighbours manage nuisance barking safely and humanely. Let’s explore how these devices work, when they’re effective, and what you should know before purchasing one.
How do anti bark devices work?
Ultrasonic anti-barking devices emit high-frequency sound waves (around 25kHz) that dogs can hear but humans cannot. When activated, these sounds interrupt a dog’s concentration and encourage them to stop barking.
Our devices, like the DAZER II,HUSH U20 and HUSH UB122, are handheld and portable, allowing you to use them indoors or outdoors. They are safe, humane, and easy to use, making them a powerful tool for controlling unwanted barking.
Ultrasonic dog barking devices are effective for:
Bark control – helping to stop excessive barking
Repelling stray or loose dogs – creating a safe space when approached
Training – discouraging unwanted behaviours in dogs

9 Things You Should Know About Ultrasonic Anti-Barking Devices
Understanding how to use your device effectively can make all the difference. Here are nine key points:
1) What is the best stop barking device?
Handheld ultrasonic devices are the most humane option. No shock, no sprays—just a harmless tone that interrupts barking and helps with training.
2) Best Devices for Neighbours’ Dogs?
Handheld devices allow you to control the sound directly, giving you professional-level training power. Wall-mounted devices may work initially, but dogs often learn to ignore them over time.
3) What results can you actually expect?
In short — yes, they work, but consistency matters more than the device itself.
A single activation will interrupt a dog's barking in the moment. Most dogs pause immediately when they hear the ultrasonic tone, because it's unexpected and unlike anything in their normal environment. That pause is the window you work with.
For your own dog, the device becomes more effective over time when paired with a verbal command — "quiet," "enough," or whatever you use consistently. Two or three repetitions per session is enough. The dog begins to associate the sound with the expected behaviour, and over time needs less reinforcement.
For a neighbour's dog, you won't have that training relationship — but the interruption still works. Most people find that a short burst redirects the dog long enough to break the barking cycle.
What it won't do is permanently silence a dog after one use, or work effectively if used inconsistently. Like any training tool, the results reflect how it's used.
ℹ️ Not recommended for puppies under 9 months or dogs over 8 years with diminished hearing.
4) Use Beyond Barking
These devices can help correct unwanted behaviour such as jumping, scratching, or digging. Pair with consistent verbal commands for best results.
5) Handling Aggressive Dogs
Stand face on and do not run. Activate the device as well as use firm verbal commands to startle and deter them from coming closer. It is the perfect solution for anyone who wants to keep dogs at a distance. For a long range ultrasonic anti barking device there is the HUSH UB122 that has an effective range of up to 15 Metres and the HUSH U20 with a range up to 10 Metres
6) Portability
Compact design means you can carry your device on your wrist, in your bag, or backpack—ready whenever you need it.
7) How to Check the Device
The devices have LED light indicators to show and confirm the device is working correctly. The HUSH series also have a friendly vibration feel when operated. Pet-Friendly Ultrasonic Technology is Safe and Effective - This product is carefully developed and tested with professional trainers to ensure safe and effective results.
8) Device Quality
Made from durable ABS materials, our devices come with a 12-month warranty for any quality-related issues. Please use our contact use page if you have any questions or need any help.
9) Limitations
Ultrasonic devices may not work in certain situations:
Dogs that are deaf or very young (less than 9 months) or old (8+ years) with limited hearing
Strong wind or solid objects blocking sound
Highly trained guard dogs may ignore it
Devices used beyond their effective range (U20: 10m, UB122: 15m)
Low battery or faulty device
How to Stop a Barking Dog Using an Ultrasonic Device
The device itself is straightforward — point and press. Getting consistent results is about how and when you use it.
Step 1 — React early, not late The most common mistake is waiting until the dog is in full bark before activating the device. By that point the dog is fully triggered and harder to interrupt. Aim to activate at the first sign of barking — the moment it starts, not after it's been going for thirty seconds.
Step 2 — Keep activations short One to two seconds is enough. A longer press doesn't increase effectiveness — it just extends the sound. Short, sharp bursts are more startling and more effective than holding the button down.
Step 3 — Follow up immediately The ultrasonic burst creates a moment of pause. What you do in that moment matters. For your own dog, use it every time alongside a consistent verbal command — "quiet," "enough," or whatever you choose. The dog learns the pattern. For a neighbour's dog, that training relationship isn't available — read our guide on stopping a neighbour's dog barking for what works best in that situation.
Step 4 — Be consistent One activation won't train a dog. Five inconsistent ones won't either. The dogs that respond best are those whose owners use the device the same way, every time, in the same situations. Consistency is what turns an interruption into a learned behaviour. If you're unsure whether it will work for your specific situation, our "Will it work for me?" page covers the most common scenarios.
Step 5 — Match the device to the distance If you're not getting a response, range may be the issue rather than technique. The DAZER II is effective up to 7 metres, the HUSH U20 up to 10 metres, and the HUSH UB122 up to 15 metres. For a neighbour's dog through a fence or across a yard, range matters more than people expect.

What is an ultrasonic bark control device?
An ultrasonic bark control device discourages dogs from barking or attacking when the device is operated. When the dog hears these sounds, they will stop barking because it is uncomfortable for them.
You can use this device at home in public places like parks or sidewalks without worrying about bothering other people. With just one click of a button on the ultrasonic dog deterrent, you can make sure that everyone around stays safe and happy. It can also be used for training purposes and to discourage discourages unwanted behaviour in dogs such jumping on people or furniture.
How does an ultrasonic anti barking device work?
Ultrasonic device emits high frequency (25KHz) directional soundwaves when operated. Handheld is the preferred option for dog owners and neighbours for long term training and control to use as it does not affect us as it is seemingly silent due to the sound being high frequency and above our hearing register.
Dogs hear the high frequency sound, and it interrupts their concentration, and their response is to stop what they were doing. Barking is natural and we need to control when barking is allowable but using only when it is nuisance barking.
Do Stop Barking Devices Work?
Results will vary but overall results are good and please look at our reviews and from people like yourself.
Some factors that cause differing success, are breed, size, age, hearing, and training. We want you to be satisfied with anti barking devices purchased through us, so we will refund if you are not getting the results we would expect. NOTE The most common lack of success comes from hearing. Old dogs who have lost high frequency hearing ability and puppies who are yet to get their high frequency hearing.
How to Use a HUSH Anti-Barking Device
Observe your dog’s behaviour. Use the device immediately when the dog barks or misbehaves
Short bursts work best. One to two seconds is usually enough to interrupt the behaviour
Pair with verbal commands. Praise your dog when they respond correctly
Repeat consistently. Over time, your dog learns the desired behaviour
Personal Story: How We Discovered the DAZER II
In 2009, while working from home, our neighbour’s dog would bark incessantly. After trying various solutions, we discovered the DAZER II. Aiming the device over the fence for a few days we trained the dog to stop barking almost entirely. This hands-on experience led us to become Australia’s distributor of the DAZER.
