Mango Worms in Dogs: Mango worms, also known as tropical canine pests, are parasitic worms that infect dogs in tropical and subtropical areas, especially Central and South America, Africa, and Southeast Asia. These nasty little worms lay eggs on the ground which hatch into larvae called maggots. The maggots burrow into the skin of dogs and develop into adult worms over 6-8 weeks.
By removing the worms, applying medication, and keeping the area clean, most dogs will recover quickly from a mango worm infestation. Be sure to check your dog regularly if traveling to or living in tropical areas and see a vet for persistent or severe cases. Staying vigilant is the best way to keep those mango worms away from your pooch!
Causes and Risk Factors for Mango Worms
There are several factors that can put dogs at higher risk of developing mango worms.
The consumption of mangoes, especially unripe mangoes, is the primary cause of mango warms in dogs. Mangoes contain a toxin called urushiol, which can irritate a dog’s intestines and cause inflammation of the gut lining. While ripe mangoes may be less irritating, it’s best to avoid feeding any part of the mango plant to your dog.
2. Access to Mango Trees or Plants
Dogs that have access to mango trees, leaves, or plants are more likely to develop mango worms. The urushiol toxin is present throughout the mango tree, including the leaves, bark, and sap. Dogs may chew on or ingest these plant parts out of curiosity or boredom, leading to irritation of the gut.
3. Weak Immune System
Dogs with a weakened immune system are more susceptible to developing mango worms and other gastrointestinal issues. Conditions like Cushing’s disease, diabetes, or gastrointestinal disease can make a dog more prone to inflammation and infection in the gut. Senior dogs or puppies also tend to have weaker immunity, putting them at higher risk.
4. Intestinal Parasites
Intestinal parasites, such as hookworms, whipworms or roundworms, can damage the lining of a dog’s intestines and make them more vulnerable to mango warms. The additional gut inflammation caused by the mango toxin may allow parasites to penetrate deeper into the intestines. Routine deworming and parasite prevention can help reduce the risk.
Keeping your dog away from mangoes and mango plants, maintaining their general health, and performing routine deworming are the best ways to avoid mango warms. Be on alert for symptoms like diarrhea, vomiting, loss of appetite or lethargy, especially after your dog has had access to mangoes. Early diagnosis and treatment is key to preventing severe complications from this toxic reaction.

Signs and Symptoms of Mango Worms
If your dog has ingested mango, watch for these signs of mango worm infestation in the coming days and weeks. Early detection and treatment is key to preventing severe infection.
1. Vomiting or Diarrhea
Within 6-12 hours of eating mango, your dog may experience vomiting, diarrhea, or both. This is a reaction to the mango itself or the mango worm larvae. See your vet right away for medication to control symptoms and prevent dehydration.
2. Skin Lesions
Two to three weeks after exposure, small nodules or swollen areas may appear under the skin, particularly around the head and neck. These lesions indicate the mango worms have burrowed in and started maturing. Have your vet examine any suspicious lumps or irritated areas of skin.
3. Itching and Scratching
As the larvae mature into adult worms over 6-8 weeks, they may cause intense itching. Your dog may scratch, bite or chew at the skin, especially around the ears, eyes, nose and mouth. See the vet for diagnosis and to discuss treatment options, such as anti-parasitic medication.
4. Respiratory Issues
In severe cases of infestation, mango worms may enter the respiratory tract, nasal passages, throat or windpipe. This can cause coughing, sneezing, difficulty breathing or pneumonia-like symptoms. This stage is life-threatening if left untreated, so contact your vet immediately.
5. Weight Loss
Heavy mango worm infestation can lead to weight loss in dogs, as the parasites feed on tissue and blood. Lethargy or decreased appetite may also occur. Seek vet care right away for deworming, fluids and nutritional support.
Catching an infestation early is critical. If your dog shows any signs within 8 weeks of eating mango, have your vet examine them for mango worms. They can determine if precautionary deworming medication is needed, even if no worms are detected yet. Early treatment will help ensure your dog remains happy, healthy and worm-free.
Treating and Preventing Mango Worms
If your dog has mango worms, the good news is they are typically easy to treat and prevent. Here are some tips for getting rid of these pesky parasites and keeping them away in the future:
The most effective way to treat mango worms is to physically remove them. You’ll need gloves, tweezers, gauze, antiseptic, and bandages. Carefully extract the worms one by one, making sure to remove them intact, including the head. Clean the area thoroughly with antiseptic after each removal and bandage the wound. Monitor the area closely over the next week or two to ensure no infection develops and that no worms were missed.
- Soak the area in warm, salty water to help draw the worms out and loosen their grip, making them easier to extract fully in one piece.
- Apply a topical anesthetic beforehand to numb the area and reduce discomfort for your dog.
2. Prevent Re-Infestation
To prevent future infestations, practice good hygiene and protection.
- Bathe your dog regularly with a medicated shampoo containing permethrin, especially after being outside. This will kill any mango worms and eggs on their skin.
- Inspect your dog’s coat, ears and paws after being outside for any worms or larvae. Remove them immediately.
- Avoid walking your dog in areas with sand, dirt or vegetation where the worms and larvae live. Stick to concrete or gravel paths when possible.
3. Other Treatments
For heavy infestations or if removal isn’t possible, your vet may prescribe oral or topical medication to kill the worms. Ivermectin, milbemycin, and fenbendazole are common anthelmintics used to treat mango worms and other parasites. Oral steroids or antihistamines may also be given for inflammation or allergic reaction.
