Fungal Diseases in Dogs

Fungi are a large family that includes mushrooms. They live in soil and organic material. Many types of fungi spread via airborne spores. Fungus spores, which resist heat and can live for long periods without water, gain entrance to the body through the respiratory tract or a break in the skin.

Fungal diseases can be divided into two categories. There are fungi that affect only the skin or mucous membranes, such as ringworm and thrush. In the other category, the fungus is widespread and involves the liver, lungs, brain, and other organs, in which case the disease is systemic.

Treating Heartworm Disease in Dogs

When and how to treat depends on the number of heartworms, their location, any medical complications (such as congestive heart failure or liver or kidney disease), the age and condition of the dog, and the presence of circulating microfilariae. After a thorough medical examination, your veterinarian will discuss these options and recommend a treatment program based on the findings. For dogs with uncomplicated heartworm disease, the objectives are to eliminate all adult worms, kill the microfilariae (if...

Good hygiene is important when handling and caring for a dog with any fungal infection. The risk to humans is low, but these are difficult diseases to treat.


This disease is found in the central United States near the Great Lakes, the Appalachian Mountains, Texas, and the valleys of the Mississippi, Ohio, and Missouri rivers. These areas have nitrogen-rich soil that facilitates growth of the causative fungus (Histoplasma capsulatum). Spores are found in soil contaminated by the dung of bats, and chickens and other birds. Spores are breathed in by dogs, people, or other animals.

In most cases, histoplasmosis is subclinical or inapparent, occasionally producing a mild respiratory infection. There is an acute intestinal form, however, that attacks the small bowel and colon. The principal signs are weight loss and intractable diarrhea. A systemic form is characterized by fever, weight loss, vomiting, muscle wasting, coughing, enlargement of the tonsils and other lymph nodes, as well as involvement of the liver, spleen, bone marrow, eyes, skin, and, rarely, the brain.

The diagnosis is made by chest X-ray, blood studies, and identification of the histoplasma organism in cytology, biopsy, or culture specimens.

Treatment: Oral anti-fungal drugs of the imidazole group, including ketoconazole, itraconazole, and fluconazole, are particularly effective in treating histoplasmosis that is not life-threatening. In dogs with severe infections, amphotericin B is often combined with one of the imidazoles. Amphotericin B is potentially damaging to the kidneys.

Coccidioidomycosis (Valley Fever)

This is the most severe and life-threatening of the systemic fungal diseases. Coccidioidomycosis is found in dry, dusty parts of the southwestern United States, and in California and neighboring Mexico. (Note that coccidioidomycosis is not the same disease as coccidiosis, a disease caused by intestinal protozoa.)


New foster dog (no pics yet and long, sorry)

I picked up a new foster dog on Sunday. He's a 1 year old shih-tzu/peke mix. Poor baby either has some sort of skin condition that makes him really oily, or someone dunked him in oil. I'm actually thinking it's probably the second one because under all the hair and oil he has some scabbs. I had the vet check for fungal or mange, and it isn't either. Which leads me to believe someone covered him in oil as some way to "cure" a tick or flea problem. So, I've given him 4 baths already trying to get the oil off. A couple more baths should get the rest of it.
He also has an ear infection in both ears, plus either kennel cough, a URI, or distemper

It depends on what you are getting

A healthy, trained, friendly, up to date with shots dog with a health certificate from a veterinarian - that isn't a bad price on a bigger dog.
An out of control, no shots, flea and or skin condition pet that is fearful or aggressive - not so good a deal.
As rescues are charging between $400-650 for dogs and you have no clue how ill the dog may be or what its previous home, treatment, environment may have been - this is no more of a gamble than that.
Right here in NH a person who adopted a rescue dog got one with a systemic fungal infection, others have gotten dogs with parvo and distemper so a private resale may be a good deal

Is not always due to hygeine or even a simple itch. if your dog is licking enough to create a hot spot he needs to see a vet. he should be checked for any skin infections (bacterial and fungal), and if he is licking his penis, it may be a good idea to do a urinalysis just to make sure he's not licking out of discomfort from some kind of urinary infection. itching/licking that causes hot spots can also be a secondary condition of allergies. if he is itching in other places than just his penis (on a regular basis) i would definitely take that into consideration too.
ultimately, he needs to see a vet, but these are some things that you need to be aware of :o)
hope that helps. good luck!
