Introduction
Cutaneous (skin) yeast infections are common in domestic dogs and are most frequently caused by an overgrowth of Malassezia species of yeast. These infections cause a number of annoying symptoms, both for affected dogs and for their owners.
Symptoms of Canine Yeast Infection
When the normal reproduction cycle of yeast becomes out-of-control, the organisms colonize, invade and damage the dog’s skin, which sets up a cycle for accelerated yeast overgrowth. The most obvious observable symptoms of yeast overgrowth include one or more of the following:
- Intense itchiness (pruritus)
- Skin irritation and inflammation, especially in and around the ears, between the paw pads and digits (toes), on the nasal folds, anal area, armpits (axillae) and neck
- Scratching (frenzied scratching and chewing can lead to weeping sores around the neck, ears, tail base, armpits and elsewhere)
- Skin redness (erythema)
- Hair loss (alopecia)
- Scaly skin (“dandruff”)
- Greasy, oily skin
- Greasy haircoat (sometimes, so much oil is produced that the dog will leave greasy patches on its bedding)
- Foul-smelling, rancid skin (often overwhelmingly offensive to owners)
- Coarse, thickened skin
- Ear infection (severe; usually with a smelly, yellowish-green discharge)
- Raised, red crusty areas on the skin
- Weeping skin sores, usually from self-trauma
- Behavioral changes associated with pruritis and pain, such as: Depression, Loss of appetite (inappetence; anorexia), Anxiety, Aggression
Dogs at Increased Risk
Dogs of any age, gender or breed can develop yeast infections. Certain breeds are more prone to developing yeast infections, either because of genetics or because of breed characteristics such as thick, wrinkled skin that provides a moist environment for yeast overgrowth. Those breeds include the West Highland WhiteTerrier, Poodle, Basset Hound, Cocker Spaniel, German Shepherd Dog and Dachshund. Yeast infections are more common in hot, humid environments.
