The Best Dog Deterrent for Protecting Attacks

Finding the best dog deterrent to prevent attacks is paramount to staying safe – especially for those who spend a considerable amount of time outdoors.

There are a handful of deterrents on the market, and most can have an impact on an incident that involves an aggressive dog. You may not need it often, but it’s comforting to know that you have one you can trust should an incident arise.

So, let’s take a look at a few factors that come into play as you search for the best dog deterrent for an aggressive dog.

Best Dog Deterrents

Below is a list of some of the most popular choices, and some comparison information. It’s always a good idea to do some research before finding the best dog deterrent, and one that you can trust as you leave the house on a daily basis.

Take a look at a chart that we recently compiled for further side-by-side analysis of the various options available.

Air Horn Dog Deterrent

An air horn dog deterrent may deter an aggressive dog from taking action, but there is a cost. Air horns come in around 130 decibels, which is louder than a rock concert and can cause hearing damage to humans or animals.

They also contain compressed gas, which can explode due to temperature.

Ultrasonic Dog Deterrent

There are several ultrasonic dog deterrents on the market. While they may deter an aggressive dog if used correctly, there are a few usage considerations. The beam angle decreases as frequency increases, meaning you may have to be fairly close to the dog to have the desired impact. Otherwise, the volume and intensity may come into question.

In addition, ultrasonic dog deterrents run on a battery. It’s important to keep retesting that battery since you can’t tell if it’s working otherwise, or you may risk not being able to use the product when you need it the most.

Spray Dog Deterrent

A spray dog deterrent such as pepper spray can be effective in deterring an attack. There are a few drawbacks to usage, however.

Some sprays come with a cone-style spray, and those can leave a lingering cloud, that can be problematic. The last thing you want is to be feeling the effects of the pepper spray yourself, as you are trying to deter an aggressive dog. You have to account for blowback, especially if you are riding or it is windy, and this can be problematic as well. It is difficult to defend yourself if you are temporarily blinded.

Audible Dog Deterrent such as K9 Sound Defense

With the Sound Defense dog deterrent, you don’t have to worry about blowback. The noise will deter the animal, without potentially damaging your hearing or the animal’s hearing. The product is easy to use and offers a low battery indicator light, so you always know if the battery needs to be changed.



In any situation with an aggressive dog, the primary goal is to stay safe. Sprays and air horns both carry an inherent risk.

It’s up to you to weigh the pros and cons of your personal situation and find the best dog deterrent. We think that Sound Defense keeps people safe with the least amount of user risk attached.
