Ringworm is a common fungal infection in dogs, and if you’re a dog parent, it’s important to know the signs so you can get your pup treated as quickly as possible.
Despite the name, ringworm isn’t actually caused by worms. It’s a fungal infection that affects the skin, hair, and nails.
This article will cover what ringworm looks like on dogs, how to recognize it, and what steps to take if you suspect your dog has it.
What is ringworm?
Ringworm is a fungal infection of the skin, hair, and nails. Despite its name, it’s not actually caused by worms.
It’s highly contagious and can spread from animals to people and vice versa. It’s worth taking steps to avoid spreading the infection.
Several types of fungi can cause ringworm in dogs, but Microsporum canis is the most common.
What Does Ringworm Look Like on a Dog?
Ringworm in dogs doesn’t always look like a worm curled in a ring. Here’s how it often shows up:
Classic Ringworm Appearance
The classic sign of ringworm is circular or semi-circular patches of hair loss, also known as alopecia. The edges of these patches may be raised, red, and inflamed, which gives them a ring-like look. The affected skin may also be scaly, crusty, or inflamed, and you may see dandruff-like flakes.
Variations in Appearance
Ringworm doesn’t always present in that classic ring shape. Sometimes it’s more like a generalized skin lesion. Other signs of ringworm include itchiness, reddened skin, darkened skin, and scabs. The dog’s hair may become dry and brittle.
Keep in mind that some dogs can carry ringworm without showing any symptoms at all.
How does a dog get ringworm?
Dogs usually get ringworm from direct contact with an infected animal. But ringworm can also spread through infected objects. These objects, called “fomites,” include things like bedding, grooming tools, and toys.
Ringworm spores are hardy and can live in the environment for a long time – weeks or even months. Because of this, environmental contamination plays a big part in spreading ringworm. It’s important to thoroughly clean anything that might have come into contact with ringworm.
Diagnosis and Treatment
If you think your dog might have ringworm, it’s important to get a diagnosis from your veterinarian. Ringworm can look like other skin conditions, and a vet can determine the best course of treatment.
Diagnosis
Often, a vet can diagnose ringworm by examining your dog’s skin and fur under an ultraviolet lamp, called a Wood’s lamp. However, a fungal culture may be needed to confirm the diagnosis.
Treatment Options
Treatment usually involves topical or oral antifungal medications. In severe cases, your vet may prescribe an oral medication.
It’s also important to decontaminate your home environment to prevent reinfection and spread. Vacuum and steam clean, and disinfect any areas where your dog spends time. Your vet may recommend shaving the affected areas to improve the effectiveness of topical treatments.
It’s critical to complete the full course of treatment, even if the ringworm seems to be clearing up. Treatment must continue until your vet confirms that your dog has recovered.
Key Takeaways
It’s important to recognize the symptoms of ringworm in dogs as soon as possible. Early detection and treatment are essential to prevent the infection from spreading and to avoid further complications.
Ringworm can look different from one dog to the next, but circular, scaly patches are a common sign. Remember that ringworm spreads through direct contact with an infected animal or person and through contaminated environments.
If you think your dog has ringworm, see your veterinarian for diagnosis and treatment. You’ll also need to decontaminate your home to prevent reinfection and to protect other members of your household.
