A yeast infection of the skin, also called yeast dermatitis, is a common skin concern for many dogs. It occurs when a specific type of yeast is overproduced. Certain breeds of dog are more susceptible to this problem, but all dogs are at risk.XResearch source It is important to quickly eliminate a skin yeast infection. These infections are often very uncomfortable for your pet. The dogs constant scratching and chewing at their own skin can also lead to secondary infections.

What Does Yeast Diaper Rash Look Like

Diaper rash involves a reddening of the skin. But there are varying degrees, Fisher says. With a regular diaper rash, youll see splotchy, pink or rosy areas of skin in babys diaper area. The condition is limited to the skin surface and the surface remains smooth.

But a yeast diaper rash looks much redder and angrier. It could also come with red spots, says Gina Posner, MD, a pediatrician at MemorialCare Orange Coast Medical Center in Fountain Valley, California. Fisher also adds that it could be a rash with unusual borders. The edges might have tiny red dots, called satellite lesions, she says. You might also see peeling at the edges. Yeast diaper rash tends to erupt in babys folds of skin, like in the upper legs, genitals and bum.

What Are Systematic Fungal Infections In Dogs

Systematic fungal infections reach beyond the skin and invade the inner body systems of your dog. These infections can be seen in your dog’s lungs, nasal passages, bone or eyes. Below is a list of a few of the most common systematic fungal infections seen in dogs throughout the US.


Aspergillosis is a fungal infection in dogs that is caused by a number of different Aspergillus species which are found in soil all around the world. This fungus is responsible for two main types of infection in dogs:


The fungus Cryptococcus is found in soil around the world but is most abundant in areas where pigeons or other birds gather in large numbers. Dogs generally inhale the fungus, which then leads to lung infection. This fungal disease initially affects the dog’s respiratory tract, but can go on to affect the central nervous system, eyes, and skin. Symptoms of cryptococcosis in dogs range from lethargy, coughing, nasal discharge, eye problems, and skin lesions, to seizures and other neurologic abnormalities. Treating cryptococosis can be challenging. While the most common treatment is an oral antifungal medication, it may need to be administered for a year or longer. Sadly, many dogs are unable to recover from this fungal infection.

Reports Of Antifungal Resistance In Different Animal Species

Azole resistance has also been described for Aspergillus,292 but up to now reports of resistant strains derived from animals are sparse. Acquisition of azole resistance can occur under prolonged therapy. Clinically, invasive infections caused by azole-resistant A. fumigatus are challenging to treat due to the lack of therapeutic options. In humans, lipid formulations of amphotericin B can be used, and 5-flucytosine has also been recommended to be added to other therapies in patients with central nervous system infections caused by resistant isolates.307 However, both antifungals have limitations, including toxicities, which may prohibit their long-term use in both humans and animals. Depending on the mechanism of resistance, higher doses of certain triazoles may be attempted, and there is a recent report of the successful treatment of invasive aspergillosis caused by an A. fumigatus isolate harboring a TR46/Y121F/T289A mutation in a bottlenose dolphin with high dose posaconazole.308 Here, the oral solution of posaconazole was incorporated into gelatin capsules and administered with a goal of achieving trough concentrations of > 3 mg/l, which was achieved after prolonged administration and resulted in clinical improvement.

What Food Causes Yeast Infection In Dogs

RingwormNot a Worm but a Fungus  Long Beach Post

There is no specific food type that will definitely cause yeast infections in dogs. Some animals have underlying allergies to certain ingredients found in dog food though, leaving them more prone to a secondary skin infection.

Everyday ingredients like chicken or beef could cause flare ups in some dogs, so a dietary trial may need to be performed to work out what your pets individual triggers are. Unless your dog has a proven allergy, his diet will not be causing his yeast infection.

Fungal diseases in dogs occur sporadically throughout the United States. Fungi are widely spread throughout the environment, and many types of fungi are spread via airborne spores, which can potentially gain entrance to the body through the respiratory tract or skin. Fungi may either involve the skin or mucous membranes, or in some cases become widespread and involve multiple organs, including the lungs, liver, and brain. While hygiene is important in managing and handling dogs with fungal infections, treatment involves the use of specific antifungal drugs.

Dogs with weakened immune systems are most at risk for this infection.


This regional systemic fungal disease is found in the Great Lakes Region, along the Eastern seaboard and in the Mississippi River valleys. Moist, organic debris and bird droppings can rot and become fertile ground for the fungus thats commonly found in the area. If your dog inhales infected spores, he may start to exhibit symptoms.


The yeast-like fungus cryptococcosis can infect dogs that inhale the spores found in soil thats been contaminated with bird droppings.

What Causes A Yeast Infection

Yeast is a type of fungus naturally present in the environment and on the skin that grows and multiplies in warm, moist environments. There are many different types of yeast but, usually, only one type of yeast causes infections in dogs – Malassezia pachydermatis. Yeast can only be seen microscopically.

Yeast infections occur when there is an overgrowth of this yeast that is normally present on the skin. There is usually an underlying reason for the overgrowth to occur, such as allergies, oily skin, or immune-mediated disease. These infections are not contagious from dog to dog but these dogs with chronic underlying conditions may be prone to frequent yeast infections.

Topical treatments for canine yeast infection on the skin include shampoos, ointments, and wipes. Kelso says that using them will typically involve a few steps:

  • If their skin or fur is oily, waxy, or scaly, wash your dog with a degreasing shampoo. This removes the filmy buildup that blocks topical medications from working.
  • Massage an antifungal dog shampoo into the skin for 10 minutes before rinsing well. Vets usually recommend using a product that contains miconazole, clotrimazole, ketoconazole, climbazole, and terbinafine.
  • Preventing Fungal Infections In Dogs

    Fungal infections in dogs range from localized annoyances to potentially fatal systemic diseases. Prevention is not always possible, but common sense measures can help. If you live in an area where a certain type of fungal infection is endemic, avoid high risk environments.

Finally, appropriately manage any underlying health problems that increase your dogs risk for developing a fungal infection.

    Topical Treatment For Ear Yeast Infections

    Veterinary Partner says yeast infections are the most common types of ear infections in dogs. The treatment for these itchy ears include cleaning out debris and medicating the infected skin in the ear canal.

Your pup will probably not be too excited about having liquid squirted into their already itchy ear, so follow your vet’s specific instructions for how to administer the treatment at home.
