Canine ringworm is a skin disease. It has nothing to do with a worm. It is a highly contagious fungal disorder.
Cause
Canine ringworm can be caused by many different species of fungus. These fungi live deep in the skin, in the hair follicles. They can be transmitted from animal to animal, human to animal, and even animal to human. Lesions will usually develop within 12 days of exposure to the fungus.
Symptoms
There are a variety of symptoms of canine ringworm. The most common sign is a round patch of skin where the hair has fallen out. The dog’s bare skin will either be crusty or scaly. These lesions aren’t usually painful or itchy to your dog.
Diagnosis
The most common method of diagnosis for canine ringworm is through use of a Wood’s light. This is a special type of ultraviolet lamp that will cause some species of fungi to glow under the light. Canine ringworm can also be diagnosed by taking a sample of the hair near the lesions and examining them. This method can take a few weeks because fungi grow slowly.
Treatment
If your dog is diagnosed with canine ringworm, you will have a few treatment options. You can give your dog a bath with antifungal shampoo three times, waiting every other day to administer the bath. Canine ringworm can also be treated using a topical antifungal cream that is spread around the lesions. This cream is usually applied daily for a period of 10 days.
Oral medication is also effective for treating canine ringworm. These medications are typically given for a month. It is also necessary to treat the environment surrounding the dog to prevent reinfections of canine ringworm. You should destroy all items used by the dog such as combs, collars, and bedding.
Prevention
The best way to prevent canine ringworm is to limit your dog’s contact with other dogs that may be infected. You should also give your dog a bath on a regular basis.
