Recognizing and Treating Patchy Fur: Common Canine Ringworm Infection

Canine ringworm is a common fungal infection that often manifests as patchy fur loss in dogs. Understanding how to identify and treat this condition is crucial for pet owners to ensure their furry friends remain healthy and comfortable.

What is Canine Ringworm?

Ringworm, despite its name, is not caused by a worm but by a group of fungi called dermatophytes. These fungi infect the skin, hair, and nails of dogs, leading to characteristic symptoms such as circular patches of hair loss, redness, and scaling.
