Ringworm is a common fungal infection that can be easily transmitted to humans from dogs. In fact, according to the article, dogs are one of the primary carriers of ringworm.

If you have a dog that's infected with ringworm, it's essential to take precautions to prevent the infection from spreading to you. This includes washing your hands frequently, especially after handling your dog's fur or bedding.

Ringworm can be spread through direct contact with an infected dog's skin, fur, or contaminated surfaces. The fungus can also be present in the dog's environment, such as on toys, blankets, or grooming tools.

What Is Ringworm in Humans

Ringworm is a common skin infection caused by a fungus called Trichophyton, Microsporum, or Epidermophyton.

It's usually a circular, itchy rash that can appear anywhere on the body, but it's most commonly found on the scalp, face, and arms.

The rash is typically red, scaly, and may have a clear center, giving it a ring-like appearance.

Ringworm is highly contagious and can be spread through direct contact with an infected person, animal, or contaminated surface.

It's not actually a worm, but rather a fungal infection that can be treated with antifungal medications.

Ringworm can be itchy and uncomfortable, but it's usually not serious and can be cleared up with treatment.

In most cases, ringworm is not a sign of poor hygiene or poor health, but rather a common fungal infection that can affect anyone.

Causes and Transmission

Ringworm is a fungal infection that can be spread through direct contact with an infected dog.

The primary cause of ringworm transmission is through the spores of the fungus, which can survive for long periods outside of a host.

Direct contact with an infected dog's skin, fur, or saliva is the most common way to contract ringworm.

Ringworm spores can also be found in the environment, such as on contaminated bedding or grooming tools, which can then be transmitted to humans through contact.

Ringworm is a fungal infection that can affect anyone, regardless of age or health status. It's highly contagious and can spread through direct contact with an infected person or animal.

The fungus that causes ringworm is called Trichophyton, and it thrives in warm, moist environments. This fungus can be found on the skin, hair, and nails of infected individuals, making it easy to spread to others.

Ringworm can also be spread through contaminated objects, such as towels, clothing, and combs. These objects can harbor the fungus and transfer it to other people or pets.

In some cases, ringworm can be spread through contact with an infected animal, such as a cat or dog. This is especially true for people who work with animals or have pets at home.

Ringworm can be found on various parts of the body, including the scalp, face, and body, and can cause symptoms like itching, redness, and a circular rash.

The fungus that causes ringworm can survive on surfaces for a long time, making it easy to pick up and spread. This is especially true in areas like locker rooms, gyms, and petting zoos.

Ringworm is highly contagious, and people with weakened immune systems are more susceptible to infection.

Risk Variance

Young puppies are most at risk of getting ringworm due to their vulnerable immune system.

Animals with problems affecting their immune system are also more susceptible to ringworm.

Hunting dogs are at higher risk due to contact with wildlife.

This increased risk is likely due to the close contact they have with potentially infected animals in the wild.

Symptoms and Diagnosis

Ringworm in dogs can be tricky to spot, and the symptoms are varied. The most common symptom is circular patches of skin that develop scales or dandruff with hair loss (alopecia).

These patches often start small but can spread over time, and they may have a ring-like appearance. The skin might be red and can be itchy, and the remaining hairs at the edge of the area are brittle and very prone to breaking.

Ringworm can also affect the nails, causing them to be easily damaged, discolored, and malformed. A veterinarian's physical examination is necessary to evaluate the skin and the overall condition of the dog.

To diagnose ringworm, a vet may use a Wood's light to look for ringworm lesions, which can glow neon green when shined on the skin in a dark room. However, some types of lesions will not appear during this exam and further tests may be necessary.

A fungal culture is one of the best ways to definitively diagnose ringworm, done by putting a sample on a culture medium and placing it in a dark area in an attempt to grow fungal spores.

Symptoms of Ringworm

Ringworm in dogs can be tricky to spot, and the symptoms are varied.

The most common symptoms include circular patches of skin that develop scales or dandruff with hair loss (alopecia), and the remaining hairs at the edge of the area are brittle and very prone to breaking.

The skin might be red and can be itchy, and as the lesion develops, brown crusts of dried secretion can form alongside small, red, raised areas of skin (papules).

Lesions typically develop on the dog's head, ears, paws, and limbs, but can occur on any other area of the skin.

Ringworm can also affect the nails, although this presentation without skin lesions is uncommon, causing the affected nail to be easily damaged, discoloured, and malformed.

Patches of hair loss, red, scaly skin, itching, and brittle, broken claws are all common symptoms of ringworm in dogs.

Here are some specific symptoms to look out for:

  • Patches of hair loss (often on head, ears, paws, limbs)
  • Red, scaly skin
  • Itching
  • Brittle, broken claws

In mild cases, hair loss may be the only noticeable sign, but in some cases, lesions can become red, irritated, and itchy.

How Is Ringworm Diagnosed

A veterinarian's physical examination is necessary to evaluate the skin and the overall condition of the dog. This exam is crucial in identifying ringworm lesions, but it's not always a definitive diagnosis.

A Wood's light is a tool that contains ultraviolet light, which can cause some ringworm lesions to glow neon green in a dark room. However, not all types of lesions will appear under this light, so further tests may be necessary.

A sample of hair and skin may be taken to look for dermatophytes under a microscope, or a fungal culture may be necessary for a definitive diagnosis. Fungal culture is one of the best ways to diagnose ringworm.

Between 26 and 70% of M. canis and any M. gypseum or Trichophyton infections don't fluoresce under the Wood's lamp, so a negative result doesn't exclude ringworm as a diagnosis.

Fungal structures seen under the microscope usually require a culture to identify the species of fungus. Fungal culture results usually take two weeks to come back from an external laboratory, so treatment may start before a positive confirmation of the diagnosis.

A skin biopsy can be a good diagnostic tool for tricky cases, such as chronic, non-healing wounds. The biopsy will be sent to a pathologist, who can use stains to make the fungal structures easier to visualise.

Treatment and Prevention

Ringworm treatment can be a challenge, but with the right approach, you can help your dog feel better and prevent the spread of the infection. Treatment typically involves topical treatment, systemic treatment, and environmental decontamination.

Topical treatment aims to decrease the number of dermatophytes present on the dog's hair and skin, as well as the chance of transmission to other dogs and people. This can be achieved with medicated shampoos or dips, applied twice per week, or creams and sprays applied two or more times a day.

Oral anti-fungal medications are typically used in moderate to severe cases and may need to be administered for six weeks or longer. Potential side effects include nausea, vomiting, diarrhea, and loss of appetite, so it's essential to follow up with fungal cultures to determine if the treatment has been successful.

Environmental decontamination is a crucial part of treatment and will reduce the likelihood of recurrence. This involves thoroughly cleaning and disinfecting the home, including toys, bowls, and bedding, with bleach wherever possible.

Treatment Options

Treatment Options can be tailored to your dog's specific needs, but the goal is always to eliminate the fungus and prevent recurrence.

Topical treatment is often used for mild cases, involving medicated shampoos or dips, applied twice a week, and creams or sprays applied two or more times a day.

Systemic treatment is usually reserved for moderate to severe cases and involves oral anti-fungal medications like itraconazole, ketaconazole, fluconazole, and terbinafine, which can take between four and eight weeks to complete.

In some cases, a combination of both topical and systemic treatments may be necessary to effectively treat ringworm.

Environmental decontamination is a crucial part of treatment, as ringworm can survive in the environment for many months, reinfecting household members.

Cleaning and disinfecting the home, especially areas where your dog has come into contact with the fungus, can significantly reduce the amount of spores present.

Natural Home Remedies

If you prefer to treat ringworm in dogs naturally at home, it's essential to keep in mind that home remedies are generally only beneficial in the mildest of cases, such as a single localized lesion.

Trimming the hair in affected areas is not always necessary and can increase the risk of the ringworm spreading.

In mild cases, natural home remedies might be worth trying, but it's crucial to monitor your dog's condition closely and seek veterinary care if the infection worsens or doesn't improve with treatment.

Ringworm home remedies are typically most effective when used in conjunction with veterinary guidance and care, especially if your dog has a more severe case or is prone to skin infections.

How to Prevent Ringworm

Keeping your dog's skin and immune system healthy is key to preventing ringworm. Regular grooming helps reduce the risk of fungal infections and lets you pick up on any skin problems early.

You can reduce your dog's risk of ringworm infection through good hygiene and common sense. Take good care of your dog's skin and overall health.

Groom your dog regularly and visit the vet for routine wellness check-ups as recommended. Keep your dog's bedding and toys clean and dry, washing beds regularly and replacing or cleaning toys as needed.

Clean your home regularly, making sure to vacuum, mop, and wipe down your dog's areas in the process. Don't allow dogs with skin conditions or open wounds to play outside.

Ringworm spreads through spores, which are often attached to shed skin scales and hairs. Confining an affected pet to an area where it has no direct contact with other pets is essential.

Immunocompromised people and young children should avoid handling affected pets, and frequent and thorough hand washing is very important.

Veterinary Diagnosis and Treatment

Diagnosing ringworm in dogs typically involves a veterinarian's physical examination, which may include using a Wood's light to look for lesions that glow neon green under ultraviolet light. This tool helps identify the presence of ringworm.

A veterinarian may also take a sample of hair and skin to look for dermatophytes under a microscope or conduct a fungal culture to confirm the diagnosis. In complicated cases, a skin biopsy might be necessary.

Treatment usually involves prescription oral medication and topical treatments, which can be used in combination to shorten the course of the disease and prevent it from spreading.

Mild cases may be treated topically with medicated shampoos or dips, often recommended twice per week. Topical creams or sprays may be used concurrently.

Oral anti-fungal medications are typically used in moderate to severe cases and may need to be administered for six weeks or longer. Potential side effects include nausea, vomiting, diarrhea, and loss of appetite.

Environmental decontamination is crucial to reduce the likelihood of recurrence. Ringworm is hardy and can survive in the environment for many months, continuing to reinfect household members. Cleaning and disinfecting the home is essential.

Dogs with ringworm should be confined to one room of the house during treatment, and other pets should not have access to this room. The room should be cleaned twice a week during treatment, then thoroughly disinfected after recovery.

Follow-up fungal cultures are necessary to determine if the treatment has been successful. It's essential to continue medications as recommended until your veterinarian says treatment is complete.

Identifying Dog Infections

If you notice any unusual symptoms in your dog, it's crucial to consult with a veterinarian as soon as possible.

Ringworm can be tricky to spot, and it might not always present as a distinct ring-shaped patch. Thick fur can hide ringworm lesions, making them less noticeable.

Scaly, crusted skin is a common symptom of ringworm, accompanied by inflammation. The affected area might be flaky and crusted.

Thin hair, broken or sparser than normal, can also be a sign of ringworm. Hair loss can occur even if the affected area isn't completely bald.

Some dogs may itch and scratch at the affected areas, though this is not always the case. Itching and discomfort are common symptoms of ringworm.

Ringworm fungi love keratin, so the illness can cause your dog's nails to become brittle or misshapen. Nail and claw infections are a possible sign of ringworm.

More unusual symptoms of ringworm include infections under or deep within the skin, leading to nodules, ulcers, and drainage. These symptoms can be severe and require prompt veterinary attention.

Some dogs may show only mild signs of ringworm, while others can come down with obviously severe infections. Early detection is extremely important to prevent the spread of the infection.

Frequently Asked Questions

Can my dog sleep with me if he has ringworm?

It's not recommended to sleep with your dog if they have ringworm, as the fungal infection can be easily transmitted to humans through touch or contact with contaminated bedding. If your dog has ringworm, separate them from you and other pets until the infection is fully treated to prevent further transmission.
