What Happens When a Dog Has Mangoworm? — The Horrifying Parasite That Hides Under the Skin and the Unspeakable Headache

When we think about parasites in dogs, fleas, ticks, or worms in the intestine often come to mind. But there is one parasite that triggers pure shock and horror among pet lovers and veterinarians alike: the mangoworm. Known for its gruesome appearance and the disturbing videos of removal online, this parasite hides beneath a dog’s skin, creating a painful, often traumatic experience for both the animal and its owner.

What Is a Mangoworm?

The term “mangoworm” refers to the larva of the Cordylobia anthropophaga, also known as the African tumbu fly. Native to sub-Saharan Africa, this parasitic fly lays its eggs in sandy soil, dirty fabrics, or any place that dogs (or even humans) might come into contact with. When the dog lies on contaminated surfaces, the warmth of its body causes the eggs to hatch. The larvae then burrow painlessly into the skin, where they grow by feeding on the dog’s tissue.

How Does It Affect the Dog?

Once inside the dog’s skin, each larva develops inside a swollen, boil-like bump called a furuncle. The center of the bump often has a tiny hole, which the worm uses to breathe. As the worm grows over several days, the area becomes inflamed, itchy, and painful. A dog infected with mangoworms may show signs such as:

• Constant scratching, biting, or licking at certain areas

• Swelling or bumps on the skin with visible holes

• Loss of appetite or fatigue

• Whimpering or restlessness due to pain

• Secondary infections if the wound opens

• 

The Removal Process: Necessary But Traumatic

Removing mangoworms is a delicate process and should ideally be performed by a veterinarian. Each larva must be extracted carefully to avoid tearing the worm, which can cause infection or inflammation if parts remain under the skin. The process involves gently squeezing the bump or using forceps to pull the larva out whole. In many cases, a dog may be infected with dozens or even hundreds of worms, making the process emotionally draining for the owner.

Prevention and Protection

Fortunately, mangoworm infestation can be prevented through simple but consistent hygiene practices:

• Keep your dog’s bedding clean and dry, and avoid letting them sleep on bare ground.

• In high-risk areas (such as parts of Africa or tropical climates), iron or sun-dry your dog’s blankets and towels to kill any hidden eggs.

• Regular grooming and skin inspections help detect early signs.

• Use veterinarian-approved repellents when traveling or living in endemic regions.

Final Thoughts

While mangoworms may seem like something out of a horror movie, they are very real—and very preventable. For dog owners, especially in tropical regions, awareness is key. What starts as a tiny, unnoticed egg can quickly turn into a painful nightmare under your pet’s skin. Staying informed and proactive is the best way to protect your four-legged friend from this terrifying parasite.
