What Is Ringworm In Dogs?

Ringworm (Dermatophytosis) in dogs is not a worm, as mentioned earlier It’s an infection of skin, hair, or nails … and it’s caused by fungus. Microsporum canis is the most common type of dermatophyte infecting both dogs and cats.

The disease causes bald, scaly patches or acne-like bumps on the skin. These patches are usually round … hence the name ringworm. Most ringworm cases spread through contact with infected animals. Sometimes contaminated grooming tools may be to blame. 

Ringworm in a healthy adult dog should clear up on its own. But natural treatment will speed up recovery and reduce your dog’s discomfort. It’ll also lower the risk of him passing it on to other family members … both pets and humans.

Note: According to the Merck Veterinary Manual … ringworm infection is more common in young or debilitated animals and in Yorkshire Terriers.

Soak a cotton ball with the undiluted ACV and apply it topically to the affected area. Repeat up to 3 times daily

Oil Of Oregano

Oil of oregano is popular for bacterial infections … especially staph infections. But it also has antifungal properties and can help with ringworm.

Lemongrass Essential Oil

Lemongrass essential oil can help heal the ringworm wounds. And it can stop them from spreading. 

Use 3 drops of the oil diluted in 1 teaspoon of carrier oil like almond oil. Rub it 3 to 4 times a day on the affected area. 

Neem Oil

Neem oil comes from the neem tree in India, and has many medicinal uses. Its antifungal properties can help with ringworm.

Garlic’s an amazing food that has so many uses for dogs. Feeding your dog garlic can be helpful for ringworm … but you can also use it topically on the skin.

Slice a clove of garlic in half. Let it sit a few minutes to release the allicin (the main medicinal property in garlic). Then rub the cut side onto the ringworm patches on your dog’s skin. Do this 3 times a day, using a fresh clove of garlic each time. 

If you want to feed fresh garlic as well, chop it up and let it sit for 15 minutes before feeding. Give these daily amounts:

  • Small dogs ¼ clove 
  • Medium dogs ½ clove
  • Large dogs ¾ clove
  • Giant dogs 1 clove

Ringworm In Your Home

Ringworm is very contagious. You’ll need to take measures to protect yourself, your family and other pets.

  • Wash down any hard surfaces with a natural disinfectant. White vinegar with high acetic acid concentration is a good option.
