Contrary to popular beliefs, ringworm does not having anything to do with a worm. The term "ring worm" originated from the red ring that can be seen in the dog's skin.
Depending on how severe the infection is, there are a number of treatment options that you can do to treat dog ringworm. One way is by bathing your canine with anti-fungal soap or shampoo and rubbing neem oil onto the dog skin. A pet bath must be done 3 times a week or every other day.
Veterinarians also recommend griseofulvin. This medicine is given daily to an infected dog for about 30 days. Topical anti-fungal medicines may also be applied to your dog's skin to kill the fungi. The area around the lesions may be also carefully clipped down close to the skin. Be cautious when doing this in order to prevent skin irritation and infection. Another dog ringworm treatment method that is proven to be effective is a lime sulfur dip. This procedure is usually initiated twice a week for the first 2 weeks, and once weekly for 4-6 weeks.
These treatments, however, do not make immediate results. During the first few days of treatment, you will observe a sudden increase in your dog's hair loss. In the next weeks, the hair loss should stop. If not, have your dog checked again by a veterinarian for further diagnosis.
Still, the best way to prevent dog ringworm is to keep your surroundings clean at all times and to groom your canine regularly. Bad hygiene and dirty environment are the main sources of fungi that cause ringworm in dogs.
