What if you abhor the K9s or are scared of them coming close? We can totally understand because not all dogs are gently mannered and playful. Some are downright aggressive breeds capable of causing serious trauma-- both mental and physical.

Here's the list of the 7 best ultrasonic dog repellers of 2024, ensuring your safety and peace of mind when dealing with dogs, even the less friendly ones.

1. Dog Dazer II Ultrasonic Dog Deterrent - Best for Big Dogs

Top on our list comes a very moderately priced product with a high number of positive reviews. The Dog Dazer II is an excellent handheld device that uses modern ultrasonic tech to keep dogs at bay even if they’re 20 feet away! And the best part is that this model has been designed to be especially useful for deterring big dogs rather than small ones. Read more to find out about our experience.

Well, being dog owners, we often find ourselves in the company of other pet parents in the neighborhood or at the dog park. While most dogs are well-behaved, there are always some we’d like to keep our distance from. Our first tryst with this model happened right beside our house when the neighbor's German Shepherd gave us a gnarly look. A press of 1-2 seconds is all it took to get him away.

We don’t approve of any form of cruelty towards animals (or humans), so this ultrasonic “gun” works wonders to scare off mutts. All you have to do is point the machine at the dog and press the button for a couple of seconds. The LED lights up to indicate the machine is working and you barely hear any noise coming out of it. 

The build quality is simple and effective-- just what you need from a device of this sort, and can be a solid companion no matter where you go. There’s also a low battery indicator to let you know when it’s ready for charging.

The only problem we encountered while using this model was related to the machine not working on the first attempt itself. On a couple of occasions when we were testing the machine (thankfully), the LED didn’t light up and we had to press it 2-3 times before it did. This can be a big deal if not taken care of early on.

2. PetUlove Handheld Ultrasonic Dog Repeller - Best for Multi-Animal Repellent

Now, this one is more than just a dog repeller! Coming with 3 channel ultrasonic sensors, you can use this machine to scare away dogs, cats, wolves, and even snakes! Well, we didn’t try on wolves and snakes but if the company says it’s true, we believe it. Besides, if your K9 companion has the problem of barking too much, this model by PetUlove should help.

First of all, this repellant costs less than the previous model we reviewed but also has a lower number of reviews on the internet. But despite it being a newer entry, it comes with loads of additional features that will appeal to everyone. Its Dog Training Aid functionality is especially useful for correcting wrong behavior such as barking, digging, or fighting.

Now, our Corgi puppy is very mild in nature but even he gets into a frenzy sometimes after seeing a squirrel or a stray cat in the backyard. We used this ultrasonic repellent to make him go away and get calmed down. Using it is easy; you press the button as usual and the machine does the rest. The 1000mA rechargeable battery is also known to last a long time.

After-sales support is what we think deserves a special mention because so few companies do it right. In addition to 24/7 customer support, you have the option to return or replace the product if it turns out to be faulty. And the best part of using this ultrasonic repellent? It won’t cause any harm to your animals.

I must say, we were completely in love with this model till we figured out that we had to charge the batteries in time for it to work with 100% efficiency. Also, the 25-foot claim is a little exaggerated so we would recommend you use it between 5-15 feet, as usual. Do not, under any circumstance, use it to annoy your pet.

3. FIRST ALERT Bark Genie Handheld Bark Control Device - Best Budget Option

Want a slightly cheaper solution to your dog-controlling woes? You won’t be disappointed after using the Bark Genie from First Alert. Although lacking in some advanced features as compared to the first two products, this device does well to keep its promise-- to deter dogs and keep them from barking excessively. Should you try it out? Let’s see.

Well, first of all, the price is an attractive factor that we must take into account. This product costs less than the first two alternatives and has almost the same features. As far as effectiveness is concerned, the manufacturer promises it to work up to 15 feet away. We roughly tested that claim and found it to be true. No exaggeration is involved!

You can carry and use it anywhere thanks to its extremely portable design that kind of resembles a flashlight. To get the dog’s attention, all you have to do is point toward him and press the button. Like others, this machine will also emit ultrasonic sounds that only your mutt can hear and will discourage them from barking or engaging in other unwanted activities.

We used the ultrasonic sound on our dog a couple of times and it worked so well that later on we only had to reach for the machine for the dog to stop. Not saying you have to terrorize your pet pals; just let them know who’s the boss!

A persistent problem in this product category we kept on noticing was that the ultrasonic sound doesn’t work on all dogs. This device also didn’t work on every breed-- some just looked at us and continued barking, and some stopped only momentarily. We’d say this machine is best used alongside proper behavioral training your puppy might be lacking.

4. PetSafe Ultrasonic Remote Dog Trainer

Want to reward good behavior in your canine companion in addition to discouraging the bad ones? Then this model from PetSafe is what you need to get started. With over 700 positive ratings during the time of writing this review, we can vouch that people around the US loved it as much as we did. What does it do differently? Well, you’re in for a treat.

Despite costing more than other models reviewed in this guide, we believe this product is worth it for the good behavior tone alone. Unlike other devices that only work to deter away dogs, this one comes with a relaxing sound that rewards your puppy for being a good boy. So, go ahead and use it twice as much and see what that leads to.

The bad behavior ultrasonic sound is also strong enough to deter dogs from a range of up to 30ft. This is by far the boldest claim the product makes and we tested it out to see if it's true. Well, we wish it was, but according to our observation, the best max range is 25 feet. Beyond that, the results get a bit iffy, if you know what we mean.

This item might cost more but it also comes with a 9V alkaline battery included. You can buy this unit with your eyes closed because PetSafe is a brand recognized worldwide for its extensive range of pet products. However, as responsible pet parents, we must remember to use devices such as this one sparsely, or else the dogs might get traumatized or familiar with the experience.

As great as this model might be, some buyers have refunded it due to the ultrasound not working for their breeds. While we have tested on a couple of breeds, we cannot guarantee it will work on yours for sure, especially if it's a super exotic one. We suggest you read through the comments and then decide. Or take a chance anyway because you have nothing to lose.

5. Frienda LED Ultrasonic Dog Repeller

Now that you’ve read about our top 5 picks, let us present you with another product that can be a great addition. This Dog Repeller by Frienda is a pocket-friendly option for those who aren’t looking for the bells and whistles of models that cost $30 and above. What features does it offer to entice buyers? Let’s find out.

There are many reasons to like this product, with price being just one of them. We love the fact that you can buy this in the color yellow, which is a nice option to have because very few manufacturers are offering colors apart from the standard black. As far as user-friendliness is concerned, this product is as easy to use as others. All you gotta do is press the button.

Starting up for the first time, just open the battery cover and insert one 9V battery. If you want to use this as a flashlight too in some occasions that’s okay too. Moreover, this device comes with a very portable shape and size, so feel free to carry it anywhere you go. We tried this at a local park one day and it showed results up to 20 feet, as promised.

What kind of results can you expect? Well, the company says you can prevent dogs from indulging in unwanted activities such as barking, growling, chewing furniture, being hyperactive, etc. However, Frienda also states that the ultrasonic sound this produces may not be enough for large and aggressive breeds. So, take those into account before buying.

One repeller for all dogs is a great concept indeed but rarely does it work as expected. The one thing we wish was better is customer support. We tried reaching out through their official phone number and were always greeted by...crickets. Email, however, worked well and we got an answer to our question.

6. Modus Ultrasonic Bark Control Device

At this point, it’s getting hard to differentiate between different products because these are all so well-made! This is another impressive product you must try if excessive barking is plaguing you.

Like every unit on our list, this one also produces ultrasonic frequency at a range that’s safe for dogs-- big or small. At 25KHz, the sound is either not passive or too loud, so you can rest assured knowing it will grab any dog’s attention. The range isn’t bad either because 16.4 ft is close or a little more than average. So, you can use this to train your dog inside or out. 

The shape is very portable and using it is as easy as it can be. There’s an LED light to indicate the unit is switched on and emitting sound. If you don’t switch it off, the model goes into hibernate mode. To switch it off, all you gotta do is hold the power button for 10 seconds. 

The Modus Ultrasonic Bark Control Device is excellent in every way except one-- customer support. We wish that was a little better because it was quite a challenge to get in touch with them.

7. PetSafe Indoor Bark Control Unit

As the guide gets longer and reviews get shorter, we bring you another product that doesn’t need much “talking about.” We were decently impressed with the performance of this indoor unit and think it’s worth a chance.

One advantage you have with this ultrasonic repeller is that you can use it both hand-held and freestanding. In addition, you also have the choice to set it to “Auto” or “Manual” mode; Auto mode activates the ultrasonic sound whenever your dog barks while Manual is for correcting bad behavior at your discretion.  

It operates using a 9V battery and it takes up to 5-6 months to get depleted--that’s impressive. Oh, this machine’s effective range is up to 25 feet, which is pretty standard. This product is not perfect but if you plan to use it exclusively indoors, we recommend trying it out.

The only con of this unit we found is that it doesn’t randomly have any effect on some dogs. One moment a dog will quickly quiet down after hearing the sound and the next, he’ll go on barking as usual. 

What is the Best Ultrasonic Dog Repellent?

Following is a comparison table, meticulously conceived to underline the key qualities of the foremost ultrasonic dog repellents. The table scrutinizes and contrasts critical features such as the material, dimensions, weight, and effective range of each product.

Buying Guide for the Best Ultrasonic Dog Repellent 

Unless you’ve owned a dog repeller before, you’re probably not very familiar with how these things work or why you might even want one in the first place. Don’t worry; in this section, we’ll explain everything you need to know about these great devices. First, let’s start with why people use ultrasonic dog repellers. 

You can use dog repellers to either scare dogs away as intended or discourage negative behavior like excessive barking, chewing furniture, growling, etc. Sure, you might be fine with a small puppy or a non-aggressive breed getting on your nerves once in a while, but what will you do when an aggressive breed such as a pitbull or rottweiler growls at you?

If things really take a turn for the worst, you won’t even have time to realize you’re being stalked and risk being attacked soon. Even if you’re a “dog person” who can’t get enough of them, there’s no guarantee you’ll be able to handle an attack like that. Or if you’re someone who is generally afraid of dogs, then having a repeller would do wonders in your life.

How to buy the best ultrasonic dog repeller

We know there are many different products available from many different brands, so choosing the right fit for your needs may be difficult. Things might get especially tricky if you’re a first-time buyer and you believe paying a higher price equates to better quality. Let us tell you, that’s not the case! You can definitely get a reliable repellent under $20 if you know where to look and what to look for.

1. Types of repellers

• Handheld repellers: these are the most popular types of repellers because they cost less and allow you to carry them anywhere. Most of these models use either AA batteries or a 9-v battery depending on their specifications. The products we’ve reviewed here are mostly handheld models and there’s very little that could go wrong if you buy one of them.
• Stationary repellers: as the name implies, these are ultrasonic dog repellers you use at a fixed place-- usually outside of the home. Stationary repellers use a PIR (Passive Infrared) sensor to detect movement in the vicinity and get triggered when the animal bypasses the set limit. These devices work well to keep away cats, rats, squirrels, possums, and other types of rodents.

2. What animals it repels

This might come off as a surprise, but ultrasonic repellers can scare away more than just dogs. Since they come with a variety of frequency settings, you can effectively keep away many kinds of critters. For animals like dogs, foxes, and mice 13.5-19.5 KHz does the trick while raccoons, skunks, and badgers can be kept away by using 19.5-24.5 KHz. 

If you have a lawn or a garden that you want to protect from these critters then having a stationary repeller is a must! We were apprehensive about buying one at first but then put one stationary repeller in the backyard. The difference was astonishing! We would always be bothered by raccoons and bats, but they were nowhere to be found after installing the machine.

3. Effective range

The last thing you’d want is for your repeller to fail just because you’re a little too far away than you think. That’s why it’s crucial to get a device that sticks to its promises of working up to a certain distance. Most mid-range repellers work best within 5-20 ft, but there are higher-priced variants that are effective for up to 50 ft. So, choose wisely and know your device well.

4. If it doubles as a flashlight

Another great feature of these repellers is that you can use them as a flashlight when needed. We don’t exactly know what led the manufacturers to include these features, but it’s a welcome modification indeed. Though this feature does not work as a selling point, we believe you can put it to use at night, when animals tend to sneak up around the house.

5. Battery type

As we mentioned before, the type of battery your ultrasonic repeller uses also plays a role in its effectiveness. Right now, most models are either powered by AA or rechargeable batteries. Although, you could find solar-powered units too if you’re interested.

Why use ultrasonic dog repellers and not other methods?

Well, if our goal is to scare dogs away then the best way to do so is by using ultrasonic sound. The sound emitted by these machines is safe for you and the dogs, and in no way does it cause any physical or mental trauma. You should NEVER take the path of throwing rocks, beating with sticks, or other inhumane methods to scare or discipline your dog.

These repellers work effectively because they emit a high-frequency sound that comes off as extremely irritating to a dog. So irritating that most dog breeds will run away if they hear it. We also like the fact that these models are available in such portable shapes and sizes that anyone can carry them anywhere. Just point in their direction and press a button!

Ultrasonic repellers also work over long ranges of up to 20-25 ft, so you don’t have to take any chances. A lot of domesticated dogs are aggressive and attack due to a lack of proper training or care given by their owners, yet somehow they believe their pooch can do no wrong! In such cases, you should definitely use ultrasonic repellers. The dog will run away scared and the owners won’t suspect a thing.

On what breeds can you use the repellent?

Honestly, the jury is still out on this one. We have no concrete evidence that supports any claims. Some say these machines work best on large dog breeds but others say it has no effect on breeds other than smaller ones. There is no general consensus we can rely upon. However, we encourage you to try it out on both big and small dogs. Chances are you’ll be lucky on both counts like we were.

For best results, we recommend you use this machine to train your dog first and scare away other dogs (if needed), second. There’s no list of breeds that you should avoid trying the repellent on; just make sure you’re not using it excessively or scaring away dogs for fun.

Why do people use ultrasonic dog repellents?

People use ultrasonic dog repellents to scare away aggressive dogs or to discourage negative behavior in their own dogs, such as excessive barking or chewing furniture. These devices emit high-frequency sounds that are irritating to dogs, causing them to run away or stop unwanted behavior.

Why use ultrasonic dog repellents and not other methods?

Ultrasonic dog repellents are preferred over other methods because they are safe for both humans and dogs, causing no physical or mental trauma. Inhumane methods like throwing rocks or beating with sticks should never be used. Ultrasonic repellents emit a sound that is highly irritating to dogs but does not harm them.

On what breeds can you use the repellent?

There is no definitive answer regarding which dog breeds ultrasonic repellents work best on. Some claim that these devices are more effective on larger dog breeds, while others suggest they work equally well on both large and small breeds. It is recommended to try the repellent on different breeds to see the results.

Can ultrasonic dog repellents double as flashlights?

Yes, some ultrasonic dog repellents come with a built-in flashlight feature. While this feature may not be a primary selling point, it can be useful for illuminating the surroundings at night when animals are more likely to approach the house.

Based on our extensive research and analysis of various ultrasonic dog repellers, three standout products have emerged as top recommendations.

The Dog Dazer II Ultrasonic Dog Deterrent is an excellent handheld device, specifically designed for deterring big dogs and offering a user-friendly experience. The PetUlove Handheld Ultrasonic Dog Repeller provides not only effective dog deterrence but also additional features for training and behavior correction.

Lastly, the FIRST ALERT Bark Genie Handheld Bark Control Device offers a more affordable option without compromising on effectiveness, making it a suitable choice for budget-conscious dog owners.

Choosing the best ultrasonic dog repeller for your needs is not rocket science! Sometimes, you just gotta take that leap of faith and make a purchase. But if you read our guide completely, you know that being informed is always better than taking a blind chance. So, go ahead and order yours now and see how it performs.

Wish you many peaceful and scare-free dog days!
