Ringworm, a misnomer for a type of fungus that is commonly found in cats and dogs, is fairly easy to treat at home or with the aid of a veterinarian. While ringworm does not pose a health risk to most animals and often clears up on its own within four months, it can be irritating to the dog for quite some time and can be passed among species, including humans.

Bathing
-
At-home treatment should consist of a twice weekly bath with an antidandruff shampoo containing selenium sulfide, such as Selsun Blue. The affected areas, normally paws, elbows or noses, should be scrubbed as thoroughly as possible to remove fungal spores.
Topical Solutions
-
Over the counter medications for yeast infections containing miconazole can be applied to the area twice a day until symptoms are gone.
Oral Treatments
-
A vet will normally prescribe a 30-day course of an antifungal drug, typically fluconazole. Fluconazole is used to cure fugal infections in humans as well.
Lime Sulfur Dips
-
A lime sulfur dip may be recommended in severe cases of ringworm. Lime sulfur dips kill the fungus, but also leave a pet's skin very dry and may cause more irritation. The solution also reeks of rotten eggs, and is considered a last resort option.
Avoiding Reinfection
-
Because ringworm is a fungus, it spreads via spores in the air. Proper cleaning of bedding, the environment and grooming supplies is necessary to aid in the treatment of ringworm and avoid reinfection.
