Dog Repellants: Which One is The Best of 2021?

When your “furry” does his business where he shouldn’t, the trouble begins. On the other hand, you may be lucky enough to live in a house on the outskirts, away from the urban hubbub, but you don’t want other dogs to enter your garden or for yours to destroy it. In cases like these, one of the best repellants for dogs can be of great help.

Simple in appearance, right? However, the 21st century and the technological revolution have turned the shopping universe into an arduous maze. When you know how to go through it, you get a superior product, since it means that, among the immense marsh of possibilities, you have known how to find the optimal one. For this to happen here too, we have written this article!

The most important

  • Repellants for dogs are usually cheap and very useful to redirect inappropriate behaviors of your dog, such as the tendency to urinate where it should not or the irrepressible desire to nibble everything that is put within reach. Of course, they require certain constancy in their use, since they are not miraculous.
  • Currently, the best repellants for dogs are made with 100% natural ingredients or safe synthesis of pheromones that give them peace of mind. In this way, they are the safest and most respectful option for them when educating them, as well as an investment that is committed to caring for planet Earth.
  • As we will see in the purchase criteria, not all repellants for dogs are the same. If you want to prevent your dog from invading certain areas of your garden, or keep intruder dogs away, you will not need the same repellent as when you want to prevent him from marking with urine what he should not or from stopping destroying your sneakers with his bite.

What is your surprise, when, when you wake up, the sneakers that you had left out are completely destroyed by the bites of your dog. It is time to buy a repellent for dogs, but, first, you must know them thoroughly.

What exactly are dog repellants and what are they used for?

Repellants for dogs generally consist of a compound that prevents dogs from approaching, biting or urinating on the object or area on which it is sprayed. However, we also have repellers for dogs, a type of repellent that usually works by ultrasound. On the other hand, there are useful anti-stress options to redirect bad behaviors.

What are the advantages and disadvantages of using a dog repellent?

Whether it’s a cheap dog repellent or something more expensive, this product offers many more advantages than disadvantages. Although in extreme occasions the ideal is to consult an ethologist, the vast majority of canine behaviors can be controlled and redirected with one of these elements.

What kinds of repellants for dogs are there?

As you may have already deduced when consulting our list, as well as following the first question answered in this section, there are a wide variety of repellants for dogs. Not only for its presentation, but also for its approach. Because each repellent for dogs has a specific objective, something you should know if you do not want to invest in an inoperative product:

  • Repellers for dogs: Within this type, the range is very wide. In fact, we could dedicate an entire article to them. Its ultrasound-based technology is useful both to educate barking or aggressive dogs and to avoid unwanted intruders on your property (other dogs or animals).
  • Anti-bite repellants for dogs: Usually available in spray format , this type of repellants for dogs are very useful for spraying clothes, curtains or furniture that you want to keep away from the jaws of your “furry”. They usually give off a very unpleasant aroma for the dog.
  • Anti-marking dog repellents: Similar to the previous ones. In fact, many of today’s dog repellants combine both options. This variant is useful when you want to prevent your dog from urinating where it should not or is dedicated to marking, for example, the domains of your garden (plants or trees, among other elements).
  • Anti-stress sprays for dogs: This option is not exactly a repellent for dogs, but it has the same objective: to redirect inappropriate behaviors; however, in this case, in a different way: by reducing the stress of the animal. Thanks to this, visits to the vet or trips by car will become more bearable.

How do you use a repellent for dogs?

The answer to this question links to the previous section. The first thing you have to be clear about is that, depending on the type of repellent for dogs you buy.

Are repellants for dogs harmful to the dog?

Absolutely. The best repellants for dogs of today take great care of this aspect, thus trying to offer safe products for your companion on walks. More and more brands are opting for natural ingredients in their composition; And, when not, they do the impossible so that the process ends in a completely respectful solution with your dog.

Regarding scarecrow-like dog repellers, these are also harmless to your dog. Not only because they use materials that allow them to be placed in a garden or green area without you having to worry about possible negative repercussions on the environment, but because their ultrasound-based technology does not harm the animal: it only removes it.

Purchase criteria

The s. XXI is synonymous with impulsiveness: clay idols that are forgotten overnight and a selfie culture in which appearance matters more than being. Faced with such a scenario, you better not transfer this gregarious and automaton spirit to the world of shopping. For this reason, and for you to be able to guide your dog, we have prepared the following purchase criteria for you:

  • Composition
  • Kind
  • objective
  • Quantity
  • Odor


Although we have already said that, currently, the vast majority of repellants for dogs are respectful both with your pet and with the environment, you always have to be very careful. In order not to invest in something that can generate more problems than solutions, we recommend that you do not forget to take a look at the ingredients of the solution. Our future also depends on it.


As we have already indicated in the Shopping Guide, you have several types of repellants for dogs. A repellent for dogs is not the same as a repellent liquid for dogs. Remember that the first of these is usually installed in the garden or in an outdoor area, and it is also useful to prevent, by means of ultrasound, other animals from approaching your home.


If what you need is a spray, you must analyze what you want it for. In the case of repellers, the options are reduced to preventing your dog or other animals from approaching certain areas; And when it comes to whistles or controls, the same, but with the addition of avoiding unnecessary barking.


If what you need is a liquid repellent for dogs, you should invest in the appropriate amount. Assess in which areas of the house you want to use it, since the more you need to protect, the more you will require. Also, check if the product requires redosing. In these cases, our recommendation is that you stock up on two or three cans.


The vast majority of repellants for dogs interact only with the dog, so they will go unnoticed by you. However, there may be an option that, without being very unpleasant, floods your home with a not especially attractive aroma. In these situations, the best thing you can do is invest in options like Animigo and its lemony touch.


With their tongues out, drooling, dogs roam the world conquering the hearts of their own and strangers. Although their nature is kind, they do not escape anger outbursts or inappropriate behavior. In these cases, a repellent for dogs is your best ally. However, you should know which one to buy, since not all act in the same way.

In the case of repellers, you should look at their installation and ease of use (especially if it is a whistle or a remote control type repeller). Regarding the classic repellants, to buy the most appropriate one you must study factors such as the amount you need, the type that best suits your needs or the smell that the solution gives off.
