Summer is here, and it’s time for beach trips, hiking, camping, and endless outdoor activities with your furry friend. But with the beautiful weather come uninvited guests: mosquitoes.

Dog with Mosquitoes

Mosquito bites can be itchy and uncomfortable, not to mention the risk of mosquito-borne diseases. As a pet parent, you want to keep your dog safe and protect them from these pesky bugs.

In this post, we’ll share some useful tips on how to help your dog stay mosquito-free and enjoy their summer to the fullest.



Mosquitoes are definitely a problem for dogs! Not only do mosquitoes harass and bite dogs (as they do humans), mosquito bites can result in everything from an annoying itch to more serious parasitic diseases.

Mosquito bites are also a primary cause of heartworm in dogs. If your dog has more hair (e.g., a chow), they have more natural protection than a bit bull or “bully” breeds.

Regardless, those areas that show more skin e.g., nose, ears, eyelids, abdomen, groin, and inside the legs, are more prone to getting mosquito bites (and can also get sunburn).

There are plenty of things you can try to change in your environment to reduce the number of mosquitoes, for example:

  • Avoid stagnant water
  • Use products containing oil of sandalwood or citronella
  • Stay inside, especially in the early morning and evening, when mosquitoes are most active

Mosquito Repellent for Dogs

To protect your dog, do NOT use human mosquito repellents containing DEET on dogs. Instead, look for repellents formulated especially for pets that contain either permethrins or pyrethrins.

Here are some dog mosquito repellent products for your dog to try:
Flys Off Spray
Flys-Off Fly Repellent Ointment
Pet Naturals of Vermont Protect Flea & Tick Repellent Spray
All Terrain Natural Pet Herbal Armor Insect Repellent Spray

Even if you use a mosquito repellent, make sure your dog is taking a heartworm preventative, such as Heartgard Plus, and also a topical treatment and prevention of ticks, fleas, mosquitoes, biting flies, and lice, such as K9 Advantix II.(see also our article on Advantix vs Frontline).

Mosquito Bite Treatment

Luckily there are some solutions to help your dog if he does get bitten. Treat bites with an antibacterial cream (e.g., Neosporin) to keep them from becoming infected.

To help with the itchiness, you might also want to try Sulfodene or a Pet Hydrocortizone (Zymox).

Please see your veterinarian if the bites appear very large (i.e. possibly something in it) or if they do not heal or appear to be getting worse.
