Symptoms
-
The most common symptom of ringworm in dogs is a round lesion without any hair. If you look closely at the lesion, you will notice the skin has a scaled texture and with small pustules. If left untreated, the small lesion will grow bigger in size, widening its circumference. This lesions may be itchy. They most commonly appear on the head but it is not rare for them to appear on the legs, tail and feet. In some severe situations, the lesions can spread across your dog's face.
Treatment
-
If your dog is healthy and the infection is isolated, it will most likely heal within four months. If the case is severe or if it does not resolve on its own, your veterinarian has various different methods of treatment available. One option is clipping down all the hair around the lesion and applying an anti-fungal cream twice a day, like miconazole cream or Lotrimin. Another therapy is employing anti-fungal dips and shampoos. Finally, your vet may want to try oral anti-fungal medicines like griseofulvin. These medicines are generally used over several months, but they can be toxic, so make sure to follow your veterinarian's instructions.
Prevention
-
Unfortunately, there is no reliable way to prevent your dog from contracting ringworm. Common places for your dog to become infected are veterinary offices, boarding facilities or grooming shops. These facilities should disinfect tables and instruments before using them with another dog. It is also important to note that you can catch ringworm from your dog. You should wear rubber gloves when handling the lesions and make sure you wash your hands after.
