5 Best Dog Repellents and Deterrents in 2020


Although man and dog have, for ages, lived together symbiotically, it can’t be avoided that some dogs might still rely on their feral instincts, especially when they feel threatened. That’s why the best dog repellents and deterrents have gained popularity as more and more people are deciding to buy or adopt dogs as pets.

There are various types of dog deterrents in the market that you can buy, some of which can be easily applied as a spray-on, some more conventionally used as a horn while some are used as a dog whistle. No matter the form, these deterrents and repellents will, with great certainty, be able to help you fend off a pack of dogs or help control your own.


Since there are dozens of dog repellents and deterrents out there, it can be quite difficult to know which ones to buy. Fortunately, decades of research and observations have given us the knowledge that certain smells, tastes, and sounds can deter and confuse dogs.

When choosing a spray repellent or deterrent, we usually look for a product that has a bitter content, has moderate amounts of capsaicin, and more importantly, won’t harm the receiving animal. That said, below are some of the best ones in the market right now:



A Harmless Means of Interrupting Your Dog’s Barking Behavior

The Pet Corrector made by The Company of Animals is one of the best dog barking deterrents on the market. It is basically a compressed gas in a can recommended by dog trainers and behaviorists worldwide. It only contains an odorless compressed gas with no toxic chemicals or substances.

It works similarly to a spray but instead of liquid coming out, compressed air will instead hiss. The product is used to train your dog to moderate his behavior at home and outside.

It works by interrupting your pets’ unwanted behavior of barking or jumping at people using the hissing sound created by the compressed air. The hiss is similar to that of the sound made by a hissing snake or geese which distracts the dog so that you can give a command like ‘sit’ or ‘down’.

Why We Like It:
  • Effective in controlling your dog’s behavior at home
  • Great for dog training
  • One canister lasts for a long time
What We Don’t Like:
  • Requires a lot of patience



An Effective and Harmless Deterrent Spray

Petsafe Sprayshield is a dog deterrent that you can use to spray an animal who is threatening you. The spray is citronella-based, and while it’s not as effective as capsaicin, it will still be able to deter an animal.

The spray does not have as powerful effect as capsaicin does and will only cause mild irritation to a dog. However, it is advisable not to use this on rabid animals as it will likely not be able to deter them from attacking you.

Another one of its pressing drawbacks is that the clip is not properly secured with adhesive and will, with little effort, come off very easily.

Why We Like It:
  • Deters a dog without harming him
  • Easy to use
  • Comes with a safety lock and a belt clip
What We Don’t Like:
  • Ineffective against rabid animals
  • The belt clip is improperly secured and is easily removed

Effective Repellent with No Expiration

HALT is the best dog repellent spray for cyclists and runners to provide them with personal protection from a rabid animal. It sprays a spicy liquid containing an active ingredient of capsaicin.

If you are under threat from a rabid or aggressive animal, all you have to do is spray it directly in its face. HALT is essentially just pepper spray but for animals, so it doesn’t harm them on contact and instead will only irritate and confuse them to give you enough time to escape. Just remember not to point it at your face.

The spray comes in a 4.9-inch-tall canister that is very easy to grip and use. It can easily hit a target up to 10 to 12 feet away, giving you a comfortable reach. Since HALT doesn’t have an expiry date, you can essentially use this for several years and still get the same result.

Why We Like It:
  • Works very effectively against rabid animals
  • Doesn’t have an expiration date
  • Can reach up to 12 feet
What We Don’t Like:
  • Must be directly aimed at the eyes to be effective
  • Needs careful handling



Chemical-Free Spray Perfect for Training

Quit It! is a compressed air pet trainer that releases a hissing sound. It only contains compressed air and is not toxic.

It works by releasing a hissing sound that resembles that of a hissing animal like a snake or geese. It is very compact, and you can easily carry this around while you’re walking your dog. To train your dog, all you have to do is press the nozzle as your dog is barking or stealing something to interrupt them. That way, they will know that what they’re doing is bad.

Why We Like It:
  • Ideal in stopping your pets’ bad behavior
  • Works as an effective training tool
What We Don’t Like:
  • Can only be used several times
  • The nozzle comes off very easily



Sprinkler-Type Deterrent for Your Lawn

The Orbit 62100 is the best dog repellent for your lawn and backyard. It has a built-in sensor that can detect movement. Although this device is quite expensive, it is very popular amongst homeowners because it is very effective in keeping animals out of your backyard.

It comes with smart switching optimization which allows it to switch modes during day or night to conserve water and avoid high energy and water consumption.

The Orbit 62100 is heavy-duty; this means it will last for a long time outside against the elements. It runs on four AA alkaline batteries that will last up to six months. The jet of water can deter animals within the vicinity of 1600 square feet. It also acts as a secondary sprinkler to your lawn and can also connect additional sprinklers.

Why We Like It:
  • Humanely repels animals out of your home
  • Can detect when it’s night or day to make sure it activates only when you need it
  • Can detect the difference between animals and trees to save water
What We Don’t Like:
  • A bit too expensive and available only in limited stocks



Q: Does Grannick’s Bitter Apple work with other animals?

A: Yes, Grannick’s Bitter Apple contains bitter contents that proactively repels any animal trying to chew or gnaw on your furniture, your shoes, or anything they find to their liking in your house.

Q: Does every ultrasonic dog repellent work on all dogs?

A: No, some breeds may be immune to certain high-frequency sounds while some ultrasonic repellents work on a different frequency. Therefore, its power and effectiveness will largely be dependent on which frequency the device emits when you use it.

Q: Can you also use HALT against people?

A: Yes, it is technically pepper spray, albeit one that is designed for animals. However, you have to be wary of using HALT against people as it is designed specifically not to hurt animals and are only meant to irritate and confuse them.


Not every dog repellent and deterrent are the same, and while some can be used for training purposes, it’s still ideal to use other training tools such as dog training collars or invisible dog fences for such purpose.

That said, if you’re worried or scared of rabid dogs, then these products mentioned above could definitely help you.
