Natural Remedy For Ringworm In Dogs

Ringworm, a contagious fungal disease, can affect your dog’s skin, hair or claws. Usually caused by the Microsporum canis fungus, it spreads freely in the environment. Dogs with compromised immune systems or existing skin problems are more prone to infection. Ringworm symptoms include hair loss accompanied by itchy, scaly or reddened skin, usually around the face, ears, tail and paws. A fungal culture is needed for accurate diagnosis.

Disinfecting Washes

Many cases of canine ringworm will subside naturally without treatment, but the process takes several weeks. During this time, the fungus can spread to other members of the family—pets and people included.

Antiseptic soaps, such as Betadine skin cleanser or Nolvasan, will prevent a mild ringworm infection from turning into a bacterial skin infection. Wash the affected areas gently, and blot dry.

Anti-Fungal Oils

Tea tree oil is a topical antiseptic and anti-fungal. Pour it into a shallow dish, and dampen a cotton ball with the oil. Apply it directly to the affected areas. For very sensitive skin, tea tree oil can be diluted with warm water. It is safe and nontoxic.

Grapefruit seed oil is available in health food stores and from online retailers. It has anti-bacterial and anti-fungal properties and can be used to combat ringworm. Mix the oil with warm water, and apply it to the lesions. If the ringworm infection is widespread and not easily treated topically, grapefruit seed oil can be mixed with a mild shampoo. Bathe your dog thoroughly. Be sure to work the shampoo in between the toes—a favorite fungal hiding place.
