How does ringworm appear in a dog? - in detail
Ringworm in dogs is a fungal infection caused by dermatophytes, primarily Microsporum canis, Microsporum gypseum, or Trichophyton mentagrophytes. The infection begins when fungal spores come into contact with a dog’s skin, often through direct contact with an infected animal, contaminated objects, or environments such as soil, bedding, or grooming tools. These spores attach to the skin and hair follicles, where they thrive in warm, humid conditions. Dogs with compromised immune systems, young puppies, or those with existing skin injuries are more susceptible. The fungi feed on keratin, a protein found in the outer layers of the skin, hair, and nails, leading to the characteristic symptoms. Initially, small, circular, red lesions appear, often accompanied by hair loss, scaling, and crusting. The affected areas may become itchy, causing the dog to scratch or lick, which can spread the infection to other parts of the body or to other animals and humans. Over time, the lesions may enlarge or multiply, and the skin can become inflamed or infected with bacteria due to secondary infections. Early detection and treatment are crucial to prevent the spread of ringworm and to ensure the dog’s recovery.
