Dog Ringworm: Causes, Symptoms, and Treatment

Dog Ringworm (Also Known as Ringworm):

This is a fungal skin disease caused by dermatophytes that affect keratinous tissues such as hair, claws, and skin. The main characteristics include clearly defined circular patches of hair loss, exudation, and scab formation on the skin.

Dog Ringworm Fungi:

The primary fungi responsible for infections in cats and dogs are Microsporum canis, Trichophyton mentagrophytes, and Trichophyton verrucosum. These fungi are highly resistant and can withstand common disinfectants to some extent.

Epidemiology:

Dog ringworm is a relatively common fungal skin disease that damages the canine skin barrier system, leading to skin inflammation and affecting the growth and development of dogs. It is highly contagious and can affect a variety of animals and humans.

Sources of Infection:

Infected or carrier cats and dogs.

Transmission Routes:

Primarily through direct contact, but can also be spread through contaminated objects. Humid, warm climates, crowded and unclean environments, and lack of sunlight are major contributing factors to the disease.

Symptoms of Dog Skin Disease:

The eyelids, between the claws, around the ears, abdomen, and limbs are prone to this condition. Affected areas show distinct circular or annular patches of hair loss, with remnants of broken hair roots and scales or crusts covering them.

Development Process:

Initial Stage:

The skin develops redness, and the animal may become restless, frequently pawing at the affected area. The area gradually forms a layer of white scab, which, when manually removed, reveals a bleeding wound.

Advanced Stage:

The affected area may experience hair loss, dry and lackluster skin, and increased keratinization. The dog may scratch the area excessively, leading to skin abrasions, which can ooze fluid and blood, often resulting in blood clots. Dogs may also become emaciated and frequently suffer from skin suppurative inflammation.

Treatment for Skin Disease:

It is recommended to seek professional veterinary care for a systematic treatment.

Prevention of Skin Disease:

Firstly, maintain good public hygiene, regularly deworm animals, and disinfect regularly to keep the skin clean and hygienic.

Secondly, conduct regular checks for signs of ringworm and dandruff in the fur. Early prevention, early detection, early isolation, and early treatment are crucial for animals that are found to be infected.
