Ringworm, or dermatophytosis, is most commonly identified by a raised red ring-shaped mark on the skin — hence the name. While the name ringworm may make you think of a parasite, like hookworm or roundworm, ringworm isn’t actually a worm at all, but a fungal infection.3
In dogs, ringworm typically lives in the outermost layer of the skin, fur, and nails. While it’s uncomfortable for your furry friend, ringworm is not life-threatening. So if your dog gets ringworm, no need to worry — it’s completely treatable.
How Do Dogs Get Ringworm?
Ringworm is highly contagious in both dogs and humans, and is considered a zoonotic infection — meaning it can be transmitted between animals and people. It’s spread through direct contact with the fungus, usually through shedding, playing, or sharing contaminated surfaces.
Ringworm’s fungal spores can live on surfaces (like your dog’s food bowl, brush, beds, etc.) for up to 18 months.4
Ringworm in Dogs Picture
Ringworm in dogs usually appears as circular patches of hair loss, typically on multiple parts of the body. It can also appear red and inflamed, or gray and scaly.
Symptoms of Ringworm in Dogs
In addition to the tell-tale circular patch of hair loss, ringworm can cause lesions that can scab and ooze.
Because ringworm affects your pet’s skin and fur, the hair follicles can become brittle and break easily, helping spread the infection to surfaces in your home. Additionally, ringworm symptoms can sometimes extend to your pet’s claws, making them brittle and rough.
Ringworm typically isn’t itchy, so if you notice your dog scratching, they could be exhibiting symptoms of another skin condition, allergies, or another infection.
How is Ringworm Diagnosed in Dogs?
Confirming the presence of ringworm requires a veterinarian’s diagnosis. Usually, a vet will take cultures from the affected area and have it sent to the lab to test for presence of the fungus.
In some cases, vets will use an ultraviolet (UV) lamp, called a Wood’s lamp. In dogs, ringworm will glow a yellow-green color when it comes into contact with UV light. However, this isn’t always the most accurate, as not all species of the fungus react this way.
Even with this test, veterinarians will often still send out a culture to the lab for confirmation.
How to Treat Ringworm in Dogs
Once your pet has been positively diagnosed with ringworm, treatment for it generally follows a three-part regimen: topical treatment, oral medication, and environmental decontamination.
Topical treatment
The first step in treatment for ringworm in dogs is some form of topical therapy. Your vet will likely recommend a daily cream, ointment, or medicated shampoo to eliminate the surface infection. They may also recommend shaving the areas surrounding the infected patches to prevent further contamination. Topical treatments may take several months to clear up the infection.
Oral medication
Oral treatments, like antifungal medications, are used in tandem with a topical treatment to fight the infection. Oral meds often require at least 6 weeks to be successful, but, like topical treatments, can take up to several months.
Environmental decontamination
Because the fungal spores can live on surfaces and in your pet’s hair follicles for over a year, cleaning and removing pet hair from your home is an important treatment step. Make sure to regularly vacuum and disinfect surfaces to remove any contamination.
