Yeast infections in dogs are fungal infections that can affect the urinary tract, mouth, or skin, especially the skin on the ears, paws, armpits, and around skin folds or wrinkles. The ears are the parts of dogs’ bodies that most commonly show signs of yeast infections. Fungal yeasts exist in and on dogs’ bodies naturally and usually aren’t problematic, but there are many things that can cause overgrowth of yeast, including medical conditions, exposure to medications, or weakened immune systems. Malassezia pachydermatitis is the type of yeast that overgrows and causes skin and ear infections. Candida yeasts affect the digestive system, mouth, and genital areas, and they are responsible for the mouth and tongue condition known as thrush. Yeast infections can lead to discomfort, self-inflicted injuries, and secondary infections among other complications. If you see the signs of a yeast infection in your dog, consult your veterinarian for a proper diagnosis and treatment. Here is what you should know about the symptoms, causes, and treatments for yeast infections in dogs.

Treatments For Yeast Infections In Dogs
Treatment for yeast infections in dogs depends on several factors, including the location of the infection, the severity, they type of yeast, and any underlying causes that may lead to yeast overgrowth. Sometimes treating the underlying cause, such as removing allergens or discontinuing medication, may be enough to fight off the infection. Other times, additional treatment is necessary.
Antifungal and anti-yeast medication may be prescribed to treat the infection. For skin infections, topical medications may need to be applied daily or multiple times a day. The prescription may call for treatment to continue for four to seven weeks. This will depend on the affected dog’s specific needs. If your dog is diagnosed with a yeast infection, follow your veterinarian’s instructions closely, and do not discontinue treatment until they instruct you to do so, even if symptoms improve. Stopping treatment early can result in a relapse. Usually treatment is effective if it is given for the full duration of the prescription.
