Best Mosquito Repellents for Dogs

PetGuide logo

It doesn’t get better than spending time in nature with your four-legged friends, but mosquitoes can seriously ruin the mood. Not only that their constant buzzing is maddening, and that no one like scratching like crazy after being bitten by one, but these bloodsuckers can also infect your dog with a potentially fatal disease. You see, Dirofilaria immitis or heartworm is a parasite transmitted only through the bite of an infected mosquito. So, in addition to being irritating as heck, mosquitoes put your pooch at risk for heartworm disease. To make sure your dog stays safe from these pesky pests, it’s best to prevent their bite altogether- there are many mosquito repellents for dogs on the market.

We selected the best mosquito repellents for dogs- be it sprays, collars, spot on, or chewables- each of them ideally suited for different conditions and situations. Read on to find out which one is the best for your fur baby!

Top 10 Mosquito Repellents for Dogs: Flea Away Natural Flea, Tick & Mosquito Repellent Chewables

What’s the best way to get rid of any parasite? Well, it’s quite simple, really: make the environment inhospitable to them. This is the principle behind the Flea Away insect repelling chewables. Bloodsuckers, such as mosquitoes, fleas, and ticks are all attracted by C02 your pet emits- and these chewables mask it. The vitamin complex chewables rely on natural ingredients to change your pet’s body odor (in a way that’s undetectable to human nose) so that they won’t smell like a meal to every mosquito or insect out there. Also, it doesn’t hurt that these chewables are liver-flavored so you can use them as a treat, too.

Needless to say, not all insect repellents are made the same- and not all of them will suit your pet’s preferences. Every pooch is unique and what works wonders for some other dog might not do the same for your pet. That’s why it’s important to do your research before you put anything on your pet- both to make sure you’re not doing more harm than good and to save money and time. To make sure you’ve picked the right type of mosquito repellent for your pet, be sure to consider all of the features below and choose accordingly.

There are so many different types of mosquito protection out there- and the type you pick will determine both how easy the preventative treatment is to apply and how long it lasts. The most common types of mosquito repellents by application methods are:

  • Sprays
  • Spot-on topical treatments
  • Insect-repelling collars
  • Insect-repellent clothing
  • Shampoos
  • Powders
  • Wipes

It’s up to you to determine which of the options is the most convenient one. For instance, if your pet likes to swim or you want to boost the effects of the repellent in certain situations (e.g. before going in nature) then go for sprays or wipes. In case you want something that works for weeks, then spot on repellents are your go-to option. The longevity and the potency of the repellent vary with each type, and while it’s easy to assume that some are more efficient than others by default, that’s not the case- it’s important to look at the active ingredients to figure that out.

There are two main categories of mosquito repellents: those based on natural ingredients and those that use dog-safe insecticides. Naturally, depending on the amount of protection you need, your pet’s sensitivities and your own preferences- one will work better than the other. As a rule of thumb, these are the active ingredients frequently used in mosquito repellents for dogs:

  • Permethrin– an insecticide used in flea and tick preventive treatments that also deters and kills mosquitoes.
  • Pyrethrin– substance found naturally in chrysanthemums that kills mosquitoes on contact.
  • Essential oils– the overpowering scents of some essential oils are known to have a repelling effect on many insects, including mosquitoes. The most common are citronella, geranium oil, eucalyptus oil, thyme oil, clove oil, lavender oil, and lemongrass. The repellent can be based on one type of essential oil or mix more than one into one blend. While these natural solutions can be effective, the strong fragrance is an issue for some- dogs have a powerful sense of smell, and if your pooch is sensitive to harsh smells, he might be bothered by essential oils. 

Another ingredient worth mentioning- but as the one to avoid in dog mosquito repellents- is DEET. While DEET is an effective insect repellent, it is not safe for pets. In fact, DEET is toxic to dogs and can cause a range of neurological and gastrointestinal issues such as vomiting, diarrhea, and seizures.
