Why are there flies on my dog? Discover the surprise answer!

If you’ve been noticing flies on your furry friend lately, you might be wondering why these pesky insects are targeting your beloved pet. While it may seem harmless at first, flies can be a real nuisance for dogs, especially if they end up biting and causing irritation. In this article, we’ll explore some of the reasons why there are flies on your dog and what you can do about it.

Understanding Fly Behavior

Before we dive into the specific reasons why flies may be attracted to your dog, it’s important to understand a bit about fly behavior. Flies are attracted to things that are smelly, decaying, or contain moisture. They’re also drawn to warmth and light, which is why you might see them hovering around windows or light fixtures. Flies can’t bite through the skin, but they can land on open wounds or areas of the body that are moist or have a strong odor.

Reasons for Flies on Dogs

Now that we have a basic understanding of how flies behave, let’s explore some of the reasons why your dog might be attracting these pests.


Dogs that eat a lot of high-protein foods or have poor digestion may produce more smelly or moist feces, which can attract flies. If your dog’s waste isn’t properly cleaned up, or if your dog has loose stool or diarrhea, this can create an ideal environment for flies to lay eggs and develop into maggots. In addition to attracting flies, this can be a potentially dangerous situation for your dog if they ingest or come into contact with maggots.


Dogs that aren’t cleaned or groomed regularly may have excess oils, dirt, or other substances on their skin and fur that can attract flies. This is especially true for dogs with folds or wrinkles in their skin, such as bulldogs or pugs, which can trap moisture and bacteria. Dogs that spend a lot of time outdoors or in areas with high humidity may also be more likely to attract flies.

Open Wounds or Sores

If your dog has any open wounds or sores, flies may be attracted to the moist, warm environment and lay eggs on or around the area. This can be especially dangerous because the larvae can feed on the surrounding flesh and cause an infection. If you notice flies lingering around a wound or sore, it’s important to clean and treat the area right away to prevent further complications.

Ear Infections

Ear infections can cause your dog’s ears to become moist and produce a strong odor, which can attract flies. This can be a vicious cycle, as the flies can then lay eggs inside the ears and cause further irritation or infection. If your dog has chronic ear infections, it’s important to work with your veterinarian to address the underlying cause and prevent the cycle of attracting flies.

Matted or Dirty Coat

Dogs that have matted, tangled, or dirty coats may be more attractive to flies, as these areas can trap moisture, bacteria, and fungi. This can lead to inflammation, sores, and other issues that can attract flies. Additionally, the flies themselves may become trapped in the matted or dirty fur and cause further irritation.

External Parasites

Dogs that have external parasites, such as fleas or ticks, may attract flies as a secondary issue. The presence of other pests can cause wounds, inflammation, and other issues that make the dog more attractive to flies. If you notice flies on your dog as well as other pests, it’s important to address all of the issues to prevent further complications.

Preventing Flies on Your Dog

Now that we’ve explored some of the reasons why flies may be attracted to your dog, let’s talk about some ways to prevent and treat the issue.

Clean and Groom Your Dog Regularly

One of the easiest ways to prevent flies on your dog is to keep them clean and groomed. This includes regularly bathing your dog, brushing their coat to remove tangles and dirt, and trimming any excess fur around their ears or paws. If your dog has folds or wrinkles in their skin, it’s important to clean and dry these areas regularly. Additionally, be sure to clean up after your dog promptly and dispose of their waste properly.

Treat Open Wounds and Sores

If your dog has any open wounds or sores, it’s important to clean and treat the area right away to prevent further complications. This includes removing any dead tissue, cleaning with an antiseptic solution, and covering the wound with a bandage or dressing. If the wound is severe or doesn’t heal over time, it’s important to seek veterinary care.

Address External Parasites

If your dog has external parasites, it’s important to address the issue promptly to prevent further complications. This may include using flea or tick preventive medications, administering flea or tick baths, or using natural remedies to repel pests. Be sure to follow the instructions on any medications or treatments and consult with your veterinarian before using any new products.

Consult with Your Veterinarian

If you’re unsure why your dog is attracting flies, or if you’ve tried home remedies without success, it’s important to consult with your veterinarian. Your vet can help identify any underlying health issues or provide specific treatments to address the issue. They may also be able to recommend preventative measures based on your dog’s breed, size, and lifestyle.

In Conclusion

Flies on your dog can be a frustrating and potentially dangerous situation, but there are steps you can take to prevent and treat the issue. By keeping your dog clean and groomed, treating any open wounds or sores, and addressing external parasites, you can help keep your dog healthy and happy.
