Introduction
Ringworm infections in dogs are not actually caused by a worm. These infections are caused by exposure to a type of fungus. If the fungus is able to establish itself on the dog’s skin, characteristic ringworm symptoms will begin to appear. This type of infection is transmissible to people, and it can only be treated through prescription medications.
Symptoms of Ringworm
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. As the fungus progresses, the hair follicles themselves will become irritated and inflamed. Small bumps and pustules may also appear on the skin.
Another characteristic symptom of ringworm is an area of skin that is inflamed or elevated. This elevation is the result of inflamed hair follicles, and this inflammation usually takes the form of a circular or oval shape too. The absence of scratching may also be a sign of ringworm, as this type of fungus does not generally cause itching.
Ringworm in dogs normally stays on one area of the skin. This patch may grow, but it does not routinely spread throughout the entire skin surface. In cases where a dog has an impaired immune system, or another underlying medical condition, the ringworm may spread all over the dog’s skin. Ringworm can occur anywhere on a dog’s body including the face and legs.
