Oct 17,2024 | puaintapets

Fungal infections in dog paws are a common and often uncomfortable condition that can affect any breed of dog. These infections can cause itching, redness, and swelling, leading to significant discomfort for your canine friend. Understanding the causes, symptoms, and treatments of fungal infections is crucial for maintaining your dog's health. This article will provide a comprehensive overview of fungal infections in dog paws, including prevention and treatment strategies.

Why Dog Paws Get Fungal Infections?

  • Environmental factors

Moist environments are prone to fungal infections, such as during the rainy or wet seasons, when dogs' paws are susceptible to fungal infections. 

  • Decreased resistance

Dogs are susceptible to fungal infections when their resistance drops, such as when they are malnourished, weak, or applying large doses of hormones for long periods of time.

  • Contact with the source of infection

Dogs coming into contact with animals or environments that have been infected with fungus, such as playing with dogs suffering from fungal skin diseases, or touching contaminated utensils, combs, scissors, pads, etc., may cause indirect infection.

  • Skin health problems

Dogs with poor skin health, such as loose, aging skin, weak stratum corneum, and imbalanced pH, are prone to fungal infections.

What are the Common Pathogens of Fungal Foot Infections in Dogs?

Dog foot fungal infections are usually caused by the following pathogens:

  • Microsporum canis

This is the most common pathogen and can cause dermatomycosis in a wide range of animals and humans, especially in dogs. 

  • Plaster-like microsporidia

This fungus lives in the soil and can cause dermatomycosis in both animals and humans. It causes severe lesions that may lead to coat loss and skin inflammation. 

  • Microsporum anomalum

This fungus is found in a few countries, such as Australia, but has a relatively low incidence. 

  • Candida albicans

Although less common, it can also cause foot infections in dogs, manifesting as blisters and peeling skin on the toes. 

  • Microsporum canis

This fungus can also cause epidermal infections of the feet, resulting in localized symptoms such as skin peeling and itching. 

These pathogens usually thrive in moist and warm environments, so keeping your dog's living environment dry and clean is crucial to preventing fungal infections of the feet. If your dog is experiencing foot skin problems, you should consult your veterinarian for diagnosis and treatment.

How to Diagnose?

Confirming a diagnosis of a fungal infection in your dog's feet usually requires your veterinarian to perform a skin scraping or a fungal culture. These tests can help determine the exact type of infection so that the appropriate treatment can be chosen.

Symptoms of Fungal Infections in Dogs

Fungal infections in dogs usually show the following symptoms.

  1. Localized hair loss in the form of round or oval patches.
  2. Redness of the skin, which may be accompanied by flakes or scabs.
  3. Itchy skin, and the dog may frequently scratch or bite the affected area.
  4. Pimples, pustules or small pustules appear on the skin.
  5. Thickening or hyperpigmentation of the skin.
  6. In some cases, there may be skin ulcers or pus.
  7. The dog may show signs of discomfort such as loss of appetite or depression.

Precautions

  • Fungal infections are contagious, especially in people with low immunity, so proper precautions should be taken, such as regular disinfection and avoiding close contact.
  • Treatment of fungal infections can take a long time, usually 2-4 months, and may require systemic therapy, including oral medications and topical baths.
  • During treatment, the dog's living environment should be kept dry and humidity should be avoided as the fungus is more likely to multiply in a humid environment.
  • Licking, biting or scratching of the infected area should be avoided and an Elizabethan collar may be required to prevent self-injury.
  • The dog's diet should be well balanced to boost its immunity and help fight the infection.
  • During treatment, the entire course of therapy should be followed and should not be interrupted, even if the symptoms disappear early, to minimize the risk of recurrence. 

Symptoms of  Dog Foot Yeast Infection

Dog foot yeast infections are usually characterized by redness, itching, hair loss, thickening of the skin, cracking, odor, and frequent licking or chewing of the affected foot by the dog. In some cases, skin ulcers or pus may develop . 

1)Causes of Infection

Yeast infections are usually caused by compromised natural defense mechanisms of the skin, such as damaged skin, a low functioning immune system, or a moist environment. The feet of dogs are a common site for yeast growth, especially between the toes, as these areas tend to stay moist and provide an ideal environment for yeast to grow. 

2)Characteristics of Yeast Infections

Caused by yeasts, such as Malassezia, these microorganisms are normally present on your dog's skin but can overgrow under certain conditions leading to infection.
Symptoms include itchy, white, sometimes foul-smelling skin, which may become rough and thick and may change color.
The infected area may have increased oil production and crusting or dandruff.

3)Key points of identification

  • Color and texture changes

Yeast infections may cause a change in skin color from pink or red to a rough, thick gray or black. 

  • Oily skin

Excessively oily or greasy skin is a common symptom of a yeast infection. 

  • Odor

Yeast infections may produce a specific odor, sometimes described as Cheetos-like or sweet. 

  • Itching and Behavioral Changes

Dogs may scratch or rub the infected area frequently, attempting to relieve discomfort by shaking their head or licking.
 
If your dog displays any of these symptoms, especially if they persist or worsen, it is recommended that you consult your veterinarian for professional diagnosis and treatment. Your veterinarian may recommend a skin scraping or culture to confirm the type of infection and provide a treatment plan accordingly.

What Aids Can Be Used to Treat Fungal Infections in Dogs' Feet?

  • Auxiliary treatments for fungal infections in dogs' feet

In addition to medication, there are a variety of aids that can be used to help treat fungal infections in your dog's feet:

  • Maintaining good foot hygiene

Wash your dog's feet regularly and make sure they are thoroughly dry, especially the area between the toes, to minimize the chances of the fungus surviving. 

  • Use an anti-fungal spray

Spraying an anti-fungal spray can help kill the fungus and reduce the risk of infection.

  • Avoid sharing personal items

Avoid sharing items that may carry fungus, such as slippers and footbaths, with other animals to prevent cross-infection. 

Provide nutrient-rich foods such as fresh vegetables, fruits and probiotic-rich foods to boost your dog's immune system. 

  • Avoid contact with sick animals

Reduce your dog's contact with animals known to have fungal infections to prevent further infection. 

  • Regular Examinations

Regularly inspect your dog's feet for early detection and management of fungal infections. 

  • Take preventive measures

Fungal infections can be effectively prevented by keeping the environment dry and clean. 

These complementary treatments can help control fungal infections in your dog's feet and speed up the recovery process. However, they are not a substitute for professional medical treatment, and if your dog's symptoms are severe or continue to fail to improve, you should consult your veterinarian promptly.

When to See a Veterinarian

Seek veterinary care if:

  • Symptoms persist or worsen despite home treatment.
  • Your dog shows signs of severe discomfort or pain.
  • There are signs of a widespread infection, such as fever or lethargy.
  • You have a puppy, senior dog, or dog with a weakened immune system showing symptoms.

FAQs

Antifungal medication

Your veterinarian may prescribe antifungal medications, such as oral medications (e.g., itraconazole) or topical medications (e.g., ointments). These medications can help kill the fungus and reduce the symptoms of the infection. The course of medication usually needs to be continued over a period of time, following your vet's instructions.

Cleaning and disinfection

Infected skin areas can be cleaned with mild skin cleansers and antibacterial lotions. It is recommended to avoid cleansers that contain harsh ingredients that can aggravate the infection. Also, the dog's environment needs to be thoroughly cleaned and disinfected to prevent the spread of the infection.
