Mosquito Bites
To help your dog from mosquitoes, it’s vital to understand that although a dog’s fur provides a layer of defense, exposed areas such as the nose or edges of the ears remain vulnerable to mosquito bites. These bites often manifest as irritating red bumps, akin to those on human skin. More significantly, mosquitoes pose a health risk by potentially transmitting diseases to your dog. Therefore, proactive mosquito control measures are essential to safeguard your pet’s health and comfort.
Dangers of Mosquitoes
The chief danger of mosquitoes to our canine friends is heartworm disease. Heartworm is a serious condition, spread by mosquitoes, that affects millions of pets every year. When a mosquito carrying the heartworm larvae bites your dog, the larvae is passed into your dog’s tissue, where it proceeds to grow into parasitic adult worms. From there, your dog’s arteries, lungs, and heart are affected. Associated symptoms include coughing, weakness, vomiting, and trouble breathing.
Heartworm disease is the main concern when it comes to mosquitoes and our dogs, but other diseases can be spread by these pests as well. Although very rare in dogs, West Nile Virus, Systemic Lupus Erythematosus (SLE), and other diseases can be transmitted through mosquito bites.
Dealing with Mosquitoes
To help your dog from mosquitoes, ensure they are on a year-round heartworm preventative. This proactive healthcare measure is critical in shielding your dog from mosquitoes and their significant threat: heartworm disease. If your dog has not started a heartworm preventative regimen, promptly schedule an appointment with your veterinarian.

There are other steps you can take to minimize the risk of mosquitoes biting your dog in the first place. First, remove any sources of standing water around your property; mosquitoes breed in stagnant water. Outfit your home with sturdy window screens to prevent mosquitoes from getting inside. Don’t allow your dog to explore marsh areas—where mosquitoes thrive—and keep them indoors during the early morning and early evening hours, when mosquitoes tend to be most active.
How to Help Your Dog Stay Safe from Mosquitoes in 2025
What times of day are mosquitoes most active?
Mosquitoes tend to be most active during the early morning and early evening hours. During these times, the air is typically cooler and more humid, which are ideal conditions for mosquito activity. To protect dogs from the increased risk of mosquito bites—and the diseases they can carry, such as heartworm—it’s advisable to limit outdoor exposure during these peak mosquito activity periods. Keeping pets indoors during these hours can significantly reduce the risk of bites.
How exactly is heartworm transmitted through mosquito bites?
Dogs get heartworm when a mosquito carrying larvae bites and deposits these microscopic invaders into the skin. The larvae enter the bloodstream, developing over time into adult worms within the blood vessels, lungs, and heart. This invasion leads to symptoms like coughing, weakness, and breathing problems as the worms increase in number. Prevention involves year-round medications that kill heartworm larvae before they mature. Prompt veterinary visits and blood testing can reduce transmission risks. Reducing standing water and blocking mosquito entry points also limits exposure to infected mosquitoes. Stay vigilant year-round.
How long do mosquito bite symptoms typically last?
Mosquito bites on dogs can cause red, itchy bumps on areas of exposed skin such as the nose or ear edges. These symptoms usually resolve within a few days but can vary depending on the dog’s sensitivity and any allergic reactions to the mosquito’s saliva. It’s important to monitor your dog for signs of excessive scratching or irritation which could indicate a more severe reaction. If symptoms persist or you notice signs of infection, consulting a veterinarian is advisable to ensure your dog’s comfort and health.
When should you take your dog to the vet for a mosquito bite?
Monitor your dog’s behavior after a mosquito bite, as subtle changes can be the first clue that something is amiss. Your dog should see a veterinarian promptly if you notice persistent redness or swelling around the bite, if the area develops lumps or scabs, or if your dog exhibits unusual coughing, weakness, or changes in breathing. These signs can point to infection or parasites, including heartworm. Annual checkups and a consistent heartworm prevention plan help reduce risks. If your dog is overly irritated by the bite or shows signs of distress like excessive licking or scratching, a veterinary professional can assess the site and prescribe treatment if needed.
What specific steps can you take to mosquito-proof your yard?
Remove standing water from buckets, planters, and birdbaths to stop mosquitoes from breeding. Inspect and fix any leaks that create damp areas. Keep grass and shrubs trimmed to limit their resting spots. If there are outdoor water bowls for pets, empty and refill them often. Put screens on doors and windows or patch any tears so mosquitoes can’t slip inside. Avoid leaving pools of water in gutters or other containers. Consider using fans on patios; mosquitoes struggle in moving air. For extra protection, apply a pet-safe insect repellent around yard entrances.
