True or False: Ringworm in dogs is caused by a worm.

Ringworm in dogs is actually caused by a type of fungus, not a worm. The term "ringworm" can be misleading because it suggests that a worm is involved when, in fact, it is a fungal infection that affects the skin, fur, and sometimes nails. The infection is caused by dermatophytes, which are a group of fungi that thrive in warm, moist environments.

This fungal infection can occur in dogs of any age, though young or immunocompromised dogs might be more susceptible. It can affect various areas of the body, most commonly on the skin, but it is not restricted to only young dogs or limited to surface layers; it can also be more systemic in certain cases if left untreated.

Understanding that ringworm is a fungal condition clarifies the nature of the disease and aids in proper treatment and management.
