"Ringworm in dogs is caused by a fungus
found in infected soil or an infected animal that causes a skin lesion
that can appear in many different ways, but commonly causes hair loss
in specific areas along with crusted skin. Dog ringworm symptoms are
commonly found on the feet, face, underbelly and if on the feet, in the
nail beds, causing dry and cracked nails. Puppy ringworm can cover the
entire face and all feet. It is also possible for a dog to be carrying
to spread ringworm without showing any symptoms. The condition is
easily spread between pets and humans, in fact many cases in humans are
tracked back to their dogs, which is why a diagnosis of human ringworm
comes with a suggestion to have your dog tested as well. Ringworm
diagnosis is done in a vet's office with a special lamp and a fungal
culture (takes several weeks to read results). There are many treatment
options including shampoos and skin treatments. See multiple
ringworm in dogs pictures below."
Ringworm in dogs is not caused by worms. It is
actually a skin
disease caused by a fungus. It can be spread when infected dog, puppy
cat, pet or human comes in contact with another dog. The fungus lives
in hair follicles, causing the hair to
break off. It is most common to see the disease on the head, ears,
and front paws in the nail beds.
The disease looks like a circle on the dog's skin with raised edges,
but it can take on a wide variety of appearances. It
looks like the hair has been removed in a circle or patch with a pale
spot at the center. Common ringworm in dogs symptoms include crusty
skin, scaling and some redness. Odd shapes usually mean that multiple
lesions joined together. It is easier to see lesions on younger dogs.
The disease usually occurs 10 days after exposure.

Ringworm on Dogs and Humans
Ringworm in dogs can be spread between dogs, cats and humans. Children
are more likely to get the disease than adults. Once someone gets the
fungus, the spores can spread in bedding and blankets. If this is the
case you need to wash exposed garments in bleach and water.
Diagnosis of Ringworm on Dogs
Your Veterinarian can diagnose Ringworm by looking at the skin of your
dog, looking at the skin under a special ultraviolet light (called a
woods light) , or by examining a sample of your dog’s hair using a
special test (fungassay test). Tests using dogs hair usually take 1 to
Since not all types of ringworm can be detected under the woods light,
additional tests are often needed. Once your dog is
diagnosed, treatment should immediately begin.

Ringworm Treatment in Dogs
Ringworm treatment in dogs is based on the severity of the condition.
Mild cases require the use of a topical or oral medication, such as a
spot-treatment using an anti-fungal lotion or anti-fungal
medicated pet shampoo. 3 baths every other day will
help to get the fungus sports off the hairs. The lather from the
shampoo should be left on the dog for 5 minutes. Be sure to
follow the directions on the bottle.
More severely effected dogs benefit from a full-body
lime-sulfur dips such as Naturasil
for Ringworm. Dips also can be preferable to any
topical creams if your dog is prone to lick the cream off before it can
take effect. The advantage of the Naturasil approach is also
that it mixes with your dog's shampoo (or with the shampoo offered by
the manufacturer), making treatment feel routine to your dog.
Shaving your dog's hair will also help to get rid of the
Often, dog ringworm will resolve on its own. When needed, treatments do
not work overnight and often take 1 to 2 weeks. You may also see more
hair loss before it gets better. If you do not see improvement in 2
weeks, revisit your Veterinarian. If after treatment the Ringworm comes
back, it means the original treatment was too short.
It also may be a good idea to quarantine your dog in
one room until treatment is completed.

If you can, we suggest trying the Naturasil product or other
topical treatments before using a prescription based approach due to
potential side effects.
We suggest avoiding if possible the use of prescription
tablets such asGriseofulvin as these can have side effects..
These tables are given to your dog everyday for 30 days. There has to
be fat in your dogs stomach for the pills to be absorbed. You can give
your dog a canned dog food or a small amount of fat from meat to ensure
that the treatment works. THIS APPROACH SHOULD NOT BE USED DURING EARLY
PREGNANCY IN YOUR DOG.
If a prescription medication is recommended by your vet,
Itraconazole is preferred because it has fewer side effects, but as all
good things, it is more expensive than other treatments.
Preventing the Return of Ringworm in Dogs
An infected dog can spread fungus spores throughout the house. These
ringworm spores are a risk for reinfection and to humans that live in
the home. To prevent reinfection, it is necessary to clean all exposed
areas with bleach. Do the same to any fabrics that your dog came in
contact with such as blankets or bedding.
