While you may have heard of histoplasmosis in humans, fungal infection is also common in dogs. It's important to know about this condition so that you can determine whether your pet has it and how best to treat it.

Histoplasmosis is a fungal disease that can be fatal in dogs and humans alike. Histoplasma capsulatum is the fungus responsible for histoplasmosis, and it's spread by inhalation of spores from contaminated soil or bird droppings. It may also be transmitted from mother to offspring through birth canal fluids.

Histoplasmosis results in an inflammatory response that can damage your dog's organs, like his lungs or liver. The damage depends on how long he was exposed to the fungus before getting treatment for it. The symptoms also vary based on where your pet contracted the infection—

  • If it's his lungs, he'll likely have trouble breathing; 

  • If it's his liver, there will be yellowing of his skin (jaundice) due to bile flow disruption. Specialized food from Hill’s prescription diet and Purina professionals can help in strengthening the liver and immune system;

  • If it's somewhere else on his body cavity surfaces (e.g., muscles), 

Then localized swelling and other signs related directly to those areas being damaged by inflammation caused by Histoplasma spores will occur. These enter through broken capillaries beneath damaged tissue layers after being inhaled into nasal passages via dust particles from contaminated areas like birds roosting outdoors. These critters are most active outdoors during the summer months. 

How Often Can Your Dog Get Infected With Histoplasma?

While it's unlikely that your dog will contract histoplasmosis, it's still worth knowing what signs to look out for. If you think your dog has been infected, or if you have any questions about this condition in dogs, please speak to a veterinarian immediately and get the right pet meds for the treatment.

Histoplasma is a fungus found in the world's soil and is inhaled by various birds and bats. It is not contagious to humans but can cause serious health issues for some dogs.

Signs Of Histoplasmosis In Dogs

Histoplasmosis is a disease that affects the lungs and lymph nodes. Signs of histoplasmosis in dogs include fever, weight loss, and lethargy. In cats, symptoms can be more severe and may include anorexia (loss of appetite), vomiting, respiratory distress (difficulty breathing), coughing up blood or mucus from the lungs, and sudden death.

Histoplasmosis is caused by a fungus called Histoplasma capnoides. It is found in certain environments, such as soil contaminated with bird droppings or bat guano, where it has been found to survive for over 100 years without losing its infectious properties. The fungus grows best in warm climates like those found in the southeastern United States but can live anywhere there's humidity and moisture indoors or outdoors in grassy areas with trees nearby that house bats infected with this fungus.

Diagnosis And Treatment Of Histoplasmosis In Dogs

A diagnosis of histoplasmosis in your dog should be made by a veterinarian. The vet will take a blood sample and perform a test for the presence of antibodies to H. capsulatum. These tests are not commercially available, so it’s unlikely that you can get your own pet tested at home.

Treatment is straightforward if you find out that your dog has histoplasmosis. Your vet can prescribe an oral antifungal pet medicine like ketoconazole for dogs or itraconazole (Sporanox), which will clear up the infection within one week or two weeks if it was very recent at diagnosis time. Although, sometimes it may take longer than this if there were other complicating factors, such as diabetes present at the time of infection onset.


Histoplasmosis, an infectious disease caused by a fungus that can be found in soil contaminated by bird or bat droppings, is rare in dogs. However, if you suspect your dog has histoplasmosis, it's important that you take him to the vet as soon as possible so treatment and pet medication can begin. 

Dogs are more likely to get infected if exposed to contaminated soil and lick their paws or fur while grooming themselves with their mouths afterward (excess of this behavior that can cause itch is called "lick granuloma"). Cats also tend to lick their paws after being outside, which could make them too susceptible to histoplasmosis.
