What is the Best Mosquito Repellent for Dogs? Buying Guide

This applies true when you are asking “what is the best mosquito repellent for dogs”. Even dogs have their own uniqueness and the products that would work for some might not be good for others.

Knowing that it is generally crucial to buy any products that you will want to put on over your doggy. You need to ensure that you are not putting your best bud’s life at greater risk and that you save more of your money, time, and effort. So, to help you to decide what is the best mosquito repellent for dogs, try to consider the following features below:

1-Mode of application

Nowadays, there are various types of protection for mosquitoes available in the market. The types are the ones that highly determine the ease of application of the preventative treatment and the time duration that the treatment would last. Here are the most popular types of repellents according to the mode of application:

  • Sprays
  • Topical applications like ointments and creams
  • Powders
  • Shampoos
  • Wipes
  • Specialized dog collars with insect repellent feature
  • Dog tees or clothes with insect repelling property

Well, with the wide range of application method, going for the most convenient one would definitely be up to you. Generally, the sprays and wipes types are effective over nature-tripping situations. Meanwhile, spot area treatment like the topical application is good for weeks of stay over your dog’s body so the effect would stay longer. Basically, the duration of effect and potency of the mosquito repellent highly depends on its type as well.   

2-Active ingredients

In order to determine what is the best mosquito repellent for dogs, we need to know the active constituent that it has. Basically, the two major classifications of mosquito repellents for dogs include the ones that have natural ingredients and those known as dog-safe insecticides. Generally, here are the active ingredients that are commonly present on the best mosquito repellents for dogs:


This is actually an insecticide that frequently acts to prevent ticks and fleas. Aside from that, it also has the ability to deter mosquitoes.


A natural substance from chrysanthemums that generally kills any in contact mosquitoes.

Essential oils

What is the best mosquito repellent for dogs in terms of the scent is the essential oil. The natural aroma of the oils is very dominating making it effectively repel insects like mosquitoes. Depending on the type, essential oil-based repellent may generally vary. Moreover, a combination of two or more essential oils into one new blend is highly allowable.

One drawback that keeps most dogs and pet owners to turn away from using it as mosquito repellent is its strong fragrance. Since the dog has a very strong sense of smell and tends to be very much sensitive to harsh odors, they may easily get distracted by the scent of the essential oils.

A very important note to remember in using essential oils as the best mosquito repellent for dogs is to avoid clove oils and oils of pennyroyal or wintergreen. These essential oils may generally harm your dog.


DEET is actually a mosquito repellent ingredient that you should keep an eye on. However, DEET should be avoided as part of the contents of mosquito repellent for dogs. Though it is very effective, it is not safe for use in pets such as dogs and cats. The reason behind this is that DEET is highly toxic and can cause neurological and GI issues to canines.

3-Natural or Chemical

Usually, chemical mosquito repellents have very strong ingredients that are really effective. In case, your dog has skin sensitivity, you should not use this kind of mosquito repellent over them. Knowing this, natural mosquito repellents are worth-noting but the problem is that some natural essential oils may also cause some issues to dogs so better be keen on this as well.

4-Long lasting or temporary effect

There are types of mosquito repellents that generally elicit maximum protection from insects for about 4 months. They are generally powerful and highly suitable for pets. Yet, the most important thing to remember when you are asking for “what is the best mosquito repellent for dogs” is the safety of your pets.

So, in terms of the longevity of effect, it is always better to ask for the advice of the veterinarian. Moreover, if you want to be on the safer side, opt for temporary protection using mosquito repellent spray types.


Knowing your dog’s weight is really essential when you want to buy mosquito repellent with chemical components. Keep in mind that dogs and cats may develop sensitivity to some pesticides including permethrin. So, using too much mosquito repellent with this ingredient may be very toxic for pets.

The best solution for this is to consider buying based on the dog’s weight. However, mosquito repellent sprays with essential oils as ingredients do not necessitate the weight of the dog.
