Lotrimin for Ringworm in Dogs

Contrary to popular belief, ringworm is not a worm, but rather a fungus that commonly infects animals, including dogs. Ringworm is so named because it causes small "rings" to appear on the body of infected dogs. While several types of fungi can cause this condition, most cases in dogs are caused by the Microsporum canis, Microsporum gypseum or Trichophyton mentagrophytes fungi.

  1. Definition

    • Humans can also get ringworm. One popular over-the-counter medication for humans that will also work on dogs is Lotrimin, an antifungal medication that contains clotrimazole as its active ingredient. It comes in cream form and helps cure ringworm and offers relief to related symptoms, including itching, redness and irritation. Veterinarians commonly recommend Lotrimin for mild cases of ringworm in dogs.

    Application

    • Lotrimin makes more than one topical product that can be used to treat ringworm, including its AF and Ultra products. Treatment directions vary by product, so it's important to read the instructions. In dogs, Lotrimin can be used to treat mild ringworm infections. More severe infections may require additional treatment, including clipping the infected area, antifungal shampoos and lime sulfur dips, and oral medications. However, trying Lotrimin first may keep you from having to take more drastic action.

    Usage

    • As most dog owners know, their canine friends tend to lick at their skin whenever any type of lesion is present. Because Lotrimin is applied topically, your dog may lick the cream or ointment off, and ingesting it could cause harm to your dog and prevent it from doing its job. You can avoid this problem by staying close to your dog and making sure he doesn't lick areas where Lotrimin has been applied until the medication has been absorbed into the skin. You can also take your dog for a walk immediately after applying Lotrimin. By the time you return home, the medication should have dried. For lesions on the legs and paws, wrap a piece of medical tape around the area after applying Lotrimin to keep it inaccessible until the medication has been absorbed.

    Considerations

    • The sooner you begin treatment of ringworm the better the chances you'll be able to eradicate the condition by using Lotrimin or another topical, over-the-counter medication. Once you see small, hairless circles appear on your dog, begin treatment. Eventually these circles will become itchy, which will result in scratching. This will spread the infection and can result in secondary infections from broken skin. However, talk with your veterinarian first to make sure your dog can use Lotrimin. Some dogs may be allergic, and others may be taking medications with which Lotrimin can interfere.

    Prevention/Solution

    • Once your dog gets ringworm once she is more likely to contract it again. That's because infected animals shed spores wherever they go, and the spores can live in the environment for more than 18 months. Spores can be found on brushes used to groom your dog, in her bedding and anywhere the dog spends considerable time. So sanitize all areas and items that may be contaminated to prevent a recurrence.
