Ringworm is a condition that occurs when a dog becomes infected with a type of fungi known as dermatophytes. The fungi most often spreads through contact with an infected dog’s skin, fur, or claws, but it may also spread through grooming tools, bedding, or furniture which has also come into contact with the fungi.
Ringworm is a common skin disorder in people, especially among children, but it may affect people of all ages. Although its name suggests otherwise, it is caused by a fungus, not a worm.
One of the signs of ringworm in dogs is unexplained hair loss on a specific area of the body. The hair loss can sometimes take a circular pattern, or it can begin small and spread. Scaly patches of skin may develop, and the hair may break off easily.
