Mosquitoes are warm-weather pests and their bites can pose real health risks to dogs, from itchy skin to serious diseases like heartworm. But do mosquitoes bite all dogs equally, or are some dogs more prone to being their target? Let’s explore why certain dogs may attract more mosquitoes and how to protect our pups from them effectively.

Do Mosquitoes Bite Dogs?

Yes, mosquitoes do bite dogs. Just like humans, dogs have exposed skin areas that mosquitoes can easily target. Mosquitoes are attracted to warmth, carbon dioxide, and body odour, all of which dogs produce. While dogs have fur that offers some protection, areas such as the nose, ears, belly, and inner thighs are vulnerable to mosquito bites.

Are Some Dogs More Prone to Mosquito Bites?

While mosquitoes do not discriminate, certain dogs tend to get bitten more than others due to several factors:

1. Coat Type and Fur Density 

Dogs with short or thin fur are more susceptible to mosquito bites than those with thick, dense coats. Breeds like Greyhounds, Chihuahuas, and Dobermans have less fur coverage, making their skin more exposed to mosquito bites. Conversely, breeds with thick double coats, such as Huskies and Golden Retrievers, have better natural protection against bites. 

2. Body Temperature and Metabolism 

Mosquitoes are attracted to warmth, and dogs with a naturally higher body temperature may be more appealing to them. Active dogs that generate more heat due to higher metabolism, such as working breeds like Border Collies or Australian Shepherds, may be at greater risk.

3. Location and Environment

Dogs living in humid or tropical areas where mosquitoes thrive are at greater risk. Additionally, dogs that spend more time outdoors, especially during dusk and dawn when mosquitoes are most active, are more likely to be bitten.

What Do Mosquito Bites Look Like on Dogs?

Mosquito bites on dogs can be challenging to spot, especially on furry areas, but they usually appear as:

• Small, red, raised bumps. Similar to mosquito bites on humans, these may be more visible on areas with thin fur.
• Localised swelling. Some dogs may develop slight swelling around the bite.
• Excessive itching or scratching. If your dog is suddenly scratching a specific area more than usual, it could indicate a mosquito bite.
• Skin irritation or redness. In dogs with sensitive skin, bites may cause more pronounced redness or irritation.
• Hair loss or sores from excessive licking. If a dog repeatedly licks a bite, it can lead to hair loss and even open sores.

Dangers of Mosquito Bites on Dogs

Mosquito bites can be more than just an itchy annoyance. Here are some potential risks:

1. Heartworm Disease 

Mosquitoes are the primary transmitters of heartworm larvae. Once infected, these parasites grow into long worms that lodge in a dog’s heart and lungs, leading to severe health complications, including heart failure. Heartworm disease can be fatal if left untreated.

2. Allergic Reactions

Some dogs may have an allergic reaction to mosquito saliva, causing excessive swelling, itching, and discomfort. In rare cases, severe allergic reactions can lead to more serious skin infections.

3. Secondary Infections

Continuous scratching or biting at a mosquito bite can break the skin, making the area vulnerable to bacterial infections. This can result in hot spots or chronic skin issues.

4. Other Mosquito-Borne Diseases

In some regions, mosquitoes can transmit diseases like West Nile virus, which can affect both humans and animals, though it is rare in dogs.

How to Prevent Mosquito Bites on Dogs

Preventing mosquito bites is the best way to protect your dog from discomfort and serious health issues. Here’s how:

1. Use Mosquito Repellents Safe for Dogs 

Not all mosquito repellents safe for humans are suitable for dogs. Avoid DEET-based products and choose pet-friendly options. Essential oils like lemongrass, cedarwood, and lavender are commonly used in pest repellent formulas. You can make your own pet-friendly mosquito repellent but please practice safety and ensure proper dilution.

One of the top-selling natural flea & tick repellent sprays that will also work on mosquitoes is the Kin+Kind Flea & Tick Protect Spray - Lemongrass for Dogs & Cats. This is a plant-based, vet-formulated spray using lemongrass and peppermint essential oils. Each ingredient, including every essential oil, is vet approved to ensure safe concentrations for your pet. The TropiClean Natural Flea & Tick Spray for Dogs is another great option, and you can also use this on your pup’s bedding for flea and tick control. 

2. Use Protective Clothing

For dogs highly susceptible to bites or who do not tolerate mosquito spray well, consider using mosquito-proof dog clothing, such as this lightweight Insect Shield Flea & Tick Cooling Tank For Cats & Dogs or the Insect Shield Repellant Bandana for Dogs. If your pup gets bitten and scratches excessively, use an itch relief spray to soothe the irritation.

3. Keep the Environment Mosquito-Free

Start by removing all standing water sources from your property, including puddles, plant trays, and empty containers that collect rainwater. Install pet-friendly mosquito traps or electronic zappers strategically around your home's exterior.

Garden enthusiasts can enhance protection by growing natural mosquito-deterrent plants such as lavender, citronella, and marigolds throughout your outdoor spaces. For additional defence, provide your dog with a dedicated Insect Shield Flea & Tick Protection Blanket as a comfortable, protective resting spot.

4. Adjust Outdoor Activity to Avoid Peak Mosquito Hours

Mosquitoes are most active at dawn and dusk. If your location is too hot for midday outdoor activities, aim for early mornings or late evenings while taking precautions like applying pet-safe mosquito repellent and keeping play areas mosquito-free. 

5. Maintain Heartworm Prevention

Even with the best mosquito prevention, some bites are inevitable. Ensure your dog is on a regular heartworm preventive medication as recommended by your vet.

Dogs of all breeds face mosquito bite risks, but factors like coat density, body heat, and time spent outdoors can increase vulnerability for some. Beyond preventing uncomfortable itching, mosquito protection is crucial for defending your dog against dangerous conditions such as heartworm disease. We strongly encourage you to consider our recommended prevention strategies. These preventative measures ensure your canine companion stays healthy and comfortable throughout the year.
