Histoplasmosis in Dogs

Histoplasmosis is a very dangerous fungal infection for dogs, but it’s also uncommon and treatable if caught early enough. The disease is caused by the Histoplasma capsulatum fungus, which is found in soil that has been enriched with bat or bird droppings. This fungus can cause acute and chronic histoplasmosis in dogs.

Histoplasmosis can be difficult to diagnose, but it’s deadly if left untreated

Histoplasmosis is a difficult disease to diagnose, and it’s deadly if left untreated. If your dog has developed symptoms of histoplasmosis, the best thing you can do is contact your veterinarian immediately.

Your veterinarian will likely recommend that you begin treatment as soon as possible because this disease can progress quickly if it goes undiagnosed or untreated.

Histoplasmosis is a deadly but uncommon fungal infection that can affect dogs.

Histoplasmosis is a fungal infection caused by an organism called Histoplasma capsulatum, which grows in the soil of many parts of the world. The disease is often found in areas where birds or other animals have reduced populations as a result of an agricultural or land-use change—for example, after an area has been cleared for farming or development. This may mean that you’re more likely to find histoplasmosis in your backyard if you live near farmland or woodland areas.

Histoplasmosis can affect humans, but it’s more common in cats than dogs because cats hunt birds and rodents that are most likely to be infected with this fungal infection. If you suspect your cat has contracted histoplasmosis from being outside, bring them to a vet immediately for treatment with anti-fungal medication. Dogs also catch histoplasmosis from eating infected meat (such as chicken flesh), so make sure that all of your dog’s food comes from sources you trust and know are safe before giving it to him or her!

Histoplasmosis is caused by a fungus known as Histoplasma capsulatum, which lives in soils enriched with bird and bat droppings.

This infection is called histoplasmosis and it’s caused by the Histoplasma capsulatum fungus, which lives in soils enriched with bird and bat droppings.

The fungus can be spread through the air when dust containing spores from soil containing the fungus are inhaled or ingested. It takes some time for symptoms to appear after exposure, so it may be hard to determine how your dog got infected with this disease.

Healthy dogs are usually resistant to histoplasmosis and don’t become sick from exposure to the fungus.

You might be wondering, “Can I catch histoplasmosis from my dog?” The answer is no. Histoplasmosis is not a disease that is transmitted from dog to dog. Any dog can become infected by inhaling spores that are in the air, but the infection usually doesn’t cause any symptoms and goes away on its own.

Dogs can also get infected by eating soil that contains the fungus, which may lead to digestive problems and diarrhea (see Symptoms).

Dogs at most risk for developing the disease are puppies less than one year old, small breeds, and dogs with compromised immune systems. Though the infection can be severe in some cases, most dogs recover well with treatment.

Dogs that develop histoplasmosis will often have symptoms such as fever, depression, weight loss, and diarrhea or vomiting.

The symptoms of histoplasmosis in dogs include fever, depression, weight loss, diarrhea or vomiting. If your dog has any of these symptoms then you should take him to the vet immediately.

Histoplasmosis can be treated with anti-fungal medications such as ketoconazole, itraconazole and fluconazole for up to 4 weeks. In severe cases that last more than 4 weeks and involve central nervous system involvement (such as meningitis), intravenous amphotericin B may be required for 6 months or longer depending on how quickly your dog recovers from this disease.

If you have an outdoor cat who likes playing in dirt then they are likely at risk for developing this disease so make sure they stay indoors away from any contaminated soil unless they’re wearing surgical gloves while cleaning out their litter box!

Upon discovery of symptoms of the illness, veterinarians will often begin treatment before receiving positive test results.

If your dog or cat presents with symptoms of histoplasmosis, the veterinarian will often begin treatment before receiving positive test results. This is because the vet knows that it’s best to treat if there’s any chance at all that your pet has been exposed to the disease.

With this in mind, veterinarians will generally start treatment based on some combination of your pet’s symptoms and risk factors like age, breed and whether they’ve been near birds or bat droppings (the carriers of histoplasmosis).

Treatment consists of a combination of antifungal drugs and corticosteroids.

Treatment consists of a combination of antifungal drugs and corticosteroids. The antifungal drugs are used to treat the infection, while the corticosteroids are used to suppress your dog’s immune system.

Because both the fungal infection and your dog’s immune system play a role in the development of histoplasmosis, treating only one side of this equation may not be enough for complete recovery.

In the case of treating your dog for histoplasmosis, it’s important to follow your veterinarian’s instructions carefully. You should not stop the medication before the vet tells you it’s OK to do so and not until symptoms have stopped. You will also need to ensure that your pet is comfortable and stays hydrated while on treatment.


Even though histoplasmosis is a rare disease and most dogs will not develop it, it’s important to learn how to recognize the signs. This way, if you notice your dog exhibiting them, you can take him or her to a vet as soon as possible.
