Yeast Infection in Dogs: Symptoms & Treatment

Yeast infections are common in dogs, and understanding their impact on their health and happiness is essential. Read on to learn how to identify them, treat them, and prevent them from recurring.

Understanding yeast infections in dogs

A yeast infection in dogs occurs when they have an overgrowth of Malassezia pachydermatis, a fungus that naturally lives on healthy skin. If it starts growing out of control, your pet will experience discomfort or signs of skin inflammation. Common triggers are underlying allergies, a weakened immune system, hormonal changes, or certain medications.

Yeast infections are most likely to occur in an area prone to moisture. Your pet can develop secondary bacterial infections, chronic inflammation, and thickened skin if left untreated. Thankfully, this is usually a very treatable problem.

Most common causes of yeast infections in dogs

Yeast thrives in warm and moist environments. This means dogs with skin folds, lots of fur, and dogs who get wet frequently are at a higher risk for developing a problem. Conditions that weaken a dog’s immune system can also increase their susceptibility.

Identifying the signs and symptoms

Recognizing an infection

A yeast infection in dogs can occur on any part of their skin, but a few areas are more prone to it.

• Ear infections: especially in dogs with floppy ears, because the ear canal proves the ideal environment for the bacteria to thrive. Signs to look for include frequent head shaking, scratching, redness, swelling, foul smell, or a brown discharge.
• Paw pads: you'll notice signs like licking, redness, and irritation between toes. Your dogs feet may develop a new, unpleasant odor. Some pet parents notice the smell of Fritos corn chips.
• Elsewhere on the body: most commonly found in skin folds, armpits, and groin. Look for redness, heat, greasy patches, a musty odor, or a scaly appearance. Hair loss from scratching or licking may further indicate a skin infection. Chronic cases may show thickened or leathery skin with brown stained fur.

Diagnosis and treatment options

It's a good idea to have your veterinarian take a look if you suspect a problem. Diagnosing a yeast infection in dogs involves examining the affected areas and running a few nonivasive tests. Treatment plans work to remove excess yeast, ease discomfort, and address underlying causes. There are also effective at-home options available that can help treat, and prevent recurring infections.

Professional diagnostic process

A thorough veterinary exam will evaluate your pet’s health history and identify possible triggers. The vet will likely ask about past skin problems, allergies, diet, and current medications.

To confirm the diagnosis, veterinarians commonly perform skin cytology tests, skin scrapings, or skin biopsy. A cytology test involves examining a sample of skin cells or ear discharge under a microscope to determine whether Malassezia yeast is present.

Standard treatment options include:

• Topical treatments: Apply these directly to the infected area to kill the yeast and lower skin inflammation. If only one area is affected, this may be all that's needed.
• Oral medications: Used for severe or persistent infections. Oral antifungal drugs, such as fluconazole or itraconazole, work throughout the body to target the yeast.

Effective home remedies

To help prevent a yeast infection in dogs, it’s essential to keep your dog’s skin clean and dry, especially after baths or swimming, and use veterinary-approved ear cleaners. Regular veterinary care and maintaining good hygiene at home are helpful ways to try to prevent skin infections. Wash your dog’s bedding often, to reduce moisture and bacteria which may contribute to infections.

If your pet develops a yeast infection, at-home remedies can provide relief. However, always talk with your veterinarian to ensure your home remedies don’t interfere with prescribed treatments.

• Medicated shampoo: Bathe your dog twice weekly with a medicated shampoo, leaving it on for 5-10 minutes before rinsing thoroughly. It contains antifungal agents that kill yeast and soothe irritated skin.
• Apple cider vinegar: Diluted solution (1:1 ratio with water) applied topically can help restore the skin’s natural pH balance.
• Probiotics: Supplementing with probiotics can help support a healthy gut microbiome, to and boost the immune system.
• Dietary changes: Eliminate any foods that could be a trigger for underlying allergies. Talk to your vet about an elimination diet.

Preventative measures

Avoiding future yeast infections requires building a strong immune system, regular grooming, and managing the moisture hiding in warm areas.

Role of diet in managing yeast infections

A strong diet is critical in managing your pet's health - the best medicine is prevention. You should work with your vet to see if your dog has any food allergies that might impact its immune system. The most common allergens are beef, chicken, dairy, wheat, and soy. Focus on high-quality, balanced food to support your dog’s overall health.

Conclusion

Understanding yeast infections in dogs helps you recognize symptoms early and seek proper care. By paying attention to their hygiene and diet, addressing underlying health issues, and talking with your vet if you have concerns, you can effectively manage and prevent yeast infections, keeping your pet happy and healthy.
