Dogs are lucky enough to have a layer of fur to keep them warm in winter and cool in summer but whilst a dog’s coat is a clever insulator, it cannot protect them against nasty insect bites and stings. Much like us, dogs can also be affected by mosquito bites, which not only cause irritation to the skin but can be fatal if they transmit diseases such as heartworm. This is why it’s important to use mosquito repellent on your dog’s fur if they are in an area where there are mosquitos. Human mosquito repellent can be very dangerous to use (which we will talk about later) so we have reviewed the best mosquito repellent for dogs and written an essential guide covering everything you need to know about mosquito repellent for dogs.
This, by far, is one of the best mosquito repellents that we have seen on the market. It’s absolutely perfect for dogs that weigh between 21-55 Lbs and is a topical formula that is applied to your dog once and keeps working for 30 days. The thing that we love about this product is that it doesn’t just work to repel and kill mosquitos, but fleas and ticks too. These little critters don’t have to bite your dog to die – they just need to come into close contact. This means that your dog doesn’t have to suffer from uncomfortable and often dangerous bites in order to be protected, they will be protected immediately on contact. The pack contains 2 x monthly applications and it’s really simple to apply. This formula works within 12 x hours and will keep working for up to x 30 days.
One of the best ways to prevent your dog from a mosquito bite is to make sure they don’t go anywhere near your dog in the first place. This flea and tick yard and kennel spray also works to repel mosquitos and promises to kill mosquitoes, flea, flea larvae, and flea eggs as well as ticks – naturally. This product has been made from fully certified essential oils that are not harmful to flowers, trees, or shrubbery. You can attach a hose to the bottle for easy application and the full pack covers up to 5,000 square feet. It’s also completely refillable.
Now, this product works a little differently from the others that we have reviewed, as it works from the inside – let us explain! This is a natural vitamin complex that has been made to FDA human standards. This has been specially formulated for cats and dogs and works to create a hostile environment for fleas, ticks, and mosquitoes. There’s no chemicals or pesticides, and so it’s completely harmless for animals – you can even use this on nursing mothers. This liver-flavored vitamin complex also has the added benefit of promoting healthy skin, a shiny coat, supple joints, and less shedding. Give your dog or cat these supplements each day to build up a healthy level of protection.

Best Mosquito Repellent for Dogs Buying Guide & FAQ
In the guide below we will talk about why it’s important to use a repellent spray for your dog and discuss what you should look out for when buying one. We will also answer your most commonly asked questions, so at the end of this guide, you will know everything you need to know about dog mosquito repellents.
Why You Should Get a Mosquito Repellent for Your Dog
There are countless reasons why you should get a repellent spray with active ingredients for your pet dog. If you live in a warm area or plan to travel with your pet dog in the height of mosquito season then you wouldn’t hesitate to protect your family’s skin – your dog should be no different. As dogs tend to spend lots of time outdoors and cannot bat away annoying gnats, flies, and mosquitoes they are at a high risk of getting bitten. Mosquito bites are not only a major irritation for your dog but they can also be deadly as mosquitos carry diseases. Heartworm is a potentially life-threatening disease that your dog can catch from just one bite. This parasite can live inside your dog for up to seven years and can grow up to a foot long – adult dogs can have up to 250 worms at a time! Seriously nasty. The West Nile Virus can also be harmful to dogs and contracted through just one mosquito bite. On top of this, your dog can also have an allergic reaction to mosquito bites, which can cause swelling, shortness of breath, and loss of appetite.
It’s absolutely vital you protect your dog at all times if you are visiting a place with mosquitoes.
What to Look for in a Mosquito Spray for Dogs
There are a few things you should consider when buying a mosquito repellent:
Sensitive skin or allergies?
If your dog has sensitive skin then you will have to be careful about what you choose to apply to it. The worst thing that could happen is that you could give your dog a serious allergic reaction and cause them discomfort. Speak to your veterinarian if you have any specific questions but if your dog is sensitive we would say that it’s probably better to avoid chemical repellents.
Most insect sprays that have been designed to repel mosquitoes in humans contain an ingredient called DEET. This is a highly-effective chemical for humans but is toxic to animals if ingested – and animals do tend to lick their fur. For this reason, you should never use a bug spray that contains DEET on your dog or cat.
Natural or chemical?
Chemical repellents contain powerful ingredients that are usually very effective. These are often not suitable for pets that have sensitive skin or allergies. You might like to consider a natural repellent spray made from essential oils and natural active ingredients but look out as even some natural oils can cause problems for your dog – geraniol oil has been known to cause gastrointestinal issues with some dogs. Speak to your veterinarian about essential oils to see which essential oil is best for your particular dog.
Long-lasting or temporary?
Some insect repellents have been designed to keep your pet protected for up to x 4 months. These are normally quite powerful solutions that may not be suitable for your pet. Again – it’s always best to speak to your veterinarian. You can buy temporary pet sprays that can instantly kill fleas and flea eggs and offer temporary protection against mosquitoes.
You should always check the weight of your pet before using any chemical mosquito spray. Dogs and cats can be very sensitive to certain pesticides such as permethrin and it can be harmful to give them too much. So always buy according to weight – if you are using a natural spray with essential oils this might not be necessary.
There is no “one-size-fits-all” answer to this question as mosquito protection can differ from product to product. Some will just require you to spray the product directly onto your pet’s fur – many pet sprays that are made from natural essential oils can normally be applied using this method. Other’s need to be added to the top of your dog or cat’s neck – and these typically last around a month or longer. Other repellents are used to spray the environment -so yards and kennels rather than topically onto your pet. Always check the instructions on the bottle as it could be harmful to use them incorrectly.
Best Mosquito Repellent for Dogs FAQ:
Q: Are dog mosquito repellents safe around my pets and children?
A: Products that have been designed to repel mosquitoes and other biting insects often contain pesticides that can be potentially harmful around children, other animals, and plants. If you are concerned about the safety of your family then you should opt for a natural repellent that has been created using essential oils. Check for products that have been FDA approved and are safe to use for humans and animals.
Q: Can I put human bug spray on my dog for protection?
A: You should never use a human bug repellent on your pet dog unless it specifically says on the packet that it is safe to do so. Human mosquito repellent often contains a chemical called DEET which is toxic to animals. It is safer to buy a product that has been specifically designed for your pet – perhaps a non-chemical option using essential oil as its main active ingredient.
Q: How do I make natural mosquito repellent for dogs?
A: If you are looking for a more natural option for your pet then you may like to consider making your own mosquito repellent using essential oil mixed with other ingredients. Although natural, essential oil can be harsh on your dog’s skin so you need to always mix the oil according to instructions and use a carrier oil that is suitable for animals. Think of your pet as no different from us – when we use new products we can often have an undesirable reaction. So it’s important to get the mix just right and always use a suitable carrier oil.
Here is a quick and easy recipe for natural mosquito repellent for dogs…
You will need:
One large glass spray bottle (as essential oil can breakdown plastic!)
15 drops lemon eucalyptus essential oil
2 oz carrier oil such as almond oil or witch hazel
All you need to do is to simply mix the ingredients in the bottle and shake well before applying to your pet. Avoid eyes, ears, and noses!
It’s always wise to test a little product on your pet to see how they react. Animals can be sensitive creatures, just like us, so we need to take care of their delicate skin.
