The next section of the article will discuss why gnats are attracted to dogs and how you can effectively keep them away from your dogs.

In the end, there will be a brief conclusion with frequently asked questions about gnats and dogs.

3 Reasons Why Gnats Are Attracted to Dogs

Reasons Why Gnats Are Attracted To Dogs

The gnats are attracted to dogs due to their body heat, carbon dioxide, odor, and long hair.

Below is a detailed discussion about each attraction.

Understanding the Gnats

Gnats may be small, but they sure can cause a lot of nuisance!

These little insects belong to the Diptera order and are usually smaller than other flying creatures like mosquitoes.

They have slender bodies and wings that make them agile flyers. You’ll mostly see them buzzing around during dusk or dawn.

1. Body Heat and Carbon Dioxide

Body Heat And Carbon Dioxide

Gnats are attracted to body heat and exhaled carbon dioxide; thus, dogs’ body heat and carbon dioxide attract gnats.

Gnats rely on these signals to find sources of food, so they flock to warm-blooded animals like dogs to feed.

2. Odor


In addition to body heat and carbon dioxide, gnats detect the unique odors from dogs, such as lactic acid, ammonia, and other compounds in their sweat or breath.

The more active dog is, and the more it sweats, the stronger these scents become-resulting in an increased likelihood of attracting gnats.

3. Long Hairs

Long Hairs

Dogs with long hairs are prime spots for Gnats to hide, breed, and feed on the oils and debris found in their fur.

These dogs are more likely to attract them than those with short hair or thinner coats due to the added protection and sustenance they provide.

Gnats are drawn to places with high moisture and humidity levels, like standing water or damp soil.

Dogs often come into contact with these environments when they drink or play, increasing the likelihood of attracting gnats.

Avoiding Standing Water

Avoiding Standing Water

Keeping Screens on Windows and Doors

Air purifiers can be an excellent solution for removing gnats in your home.
