What is Ringworm?

1. what is ringworm

Scientifically known as dermatophytes, ringworm is a collection of fungi.

In dogs, it’s mainly caused by the fungus Microsporum canis but can also be caused by the Microsporum gypseum fungus or, in smaller amounts, the Trichophyton mentagrophytes.

When on your dog, these fungi thrive in the top layer of their skin as well as in their hair follicles and even in their nails.

It can cause patchy, crusty areas on the body that can make your dog uncomfortable.

Identifying Ringworm

When a dog contracts ringworm, you’ll notice hair loss along with lesions on the skin that will tend to be in circular patterns that grow larger.

While the lesions can be itchy that isn’t always the case.

They do get inflamed and scab over, though. This, along with the hair loss, is what is typically seen when a dog has ringworm.

When a dog contracts ringworm in their nails, they can become brittle and rough.

There are some instances where a dog won’t show any symptoms.

In these cases, your dog can easily spread ringworm to other animals or even to you.

This is why any change in your dog’s behavior or any noticeable hair loss should be looked into.

What Causes Ringworm in Dogs?

2. causes of ringworm

A dog gets ringworm when they come into contact with the fungus.

If another animal or person has ringworm, they can pass it on to your dog.

Similarly, if another animal had the infection and contaminated your home, your dog could contract ringworm that way.

The spores are naturally found in the soil so if your dog is frequently outside rolling around in the mud, their risk of contracting ringworm can be higher than other dogs that prefer to stay inside.

Elderly dogs, puppies, and dogs with compromised immune systems are more prone to ringworm since they won’t be able to fight the infection as well as a young, healthy pup can.

Dogs in kennels or shelters are also more at risk for the infection due to the close quarters and ringworm’s easily spreadable nature.

What are the Symptoms of Ringworm in Dogs?

3. ringworm symptoms in dogs

While there are cases where a dog with ringworm presents as asymptomatic, in most instances classic ringworm symptoms include :

  1. Lesions in circular patterns on one or more parts of the body
  2. Patchy bald spots possibly with scabs or crusty appearance
  3. Localized broken hairs in minor infections
  4. Brittle or broken nails if the infection is found there
  5. Behavior changes in your pet including lethargy or visible discomfort

How Long does Ringworm Last in a Dog?

4. how long ringworm last

The length of a given infection depends on the severity of the case as well as your treatment plan and your dog’s immune response to that treatment.

In most cases, a dog with ringworm will be contagious for around three weeks if you properly treat your pet.

If you don’t aggressively treat your dog, the infection can last longer.

To see how the treatment is working, your vet will most likely have you come back in for multiple cultures to check your dog’s response to the medications.

You must follow the proper treatment plan even if you assume that your dog is better based on their physical appearance.

Don’t stop medications or using a ringworm shampoo earlier that your vet prescribed.

If you do this, you run the risk or re-infection or of spreading the infection to other animals and humans.

How to Treat Ringworm

5. ringworm treatments

It’s important to treat fungal infections like ringworm as soon as they’re detected so they don’t spread to other animals or you and your family.

You have to start by going to see your vet for a proper diagnosis.

They can use an ultraviolet light to examine your dog and look for signs of the fungal infection. They will also take cultures of any lesions to make a determination.

After all diagnostic tests are performed a treatment plan will be arranged.

This mainly depends on the severity of the infection and how concerned you and your vet are about the infection spreading to other pets or humans.

Usually, treatment will consist of topical medication, oral medication, and an order to decontaminate your household and any other area your dog spends most of their time in (like your yard or a dog house).

Topical treatment can be a cream along with a ringworm shampoo for dogs.

This will help heal the superficial infection and control the spread of the fungal infection. In addition to that, your vet might tell you to clip your dog’s coat if it’s long.

While a ringworm shampoo isn’t meant to treat the infection on its own, it does help control the progression of the infection and can help prevent the fungus from contaminating your dog’s environment.

Your vet might suggest that you use this shampoo on other dogs in your home to help keep them from being infected.

Oral treatment will usually consist of an anti-fungal medication while environmental decontamination will require you to clean your home thoroughly.

You should clean all areas of your home where fallen fur can accumulate. This includes furniture, the floors/rugs, bedding, and clothing.

Fallen hair follicles can actually contain fungal spores that can spread ringworm for as long as months after the fact.

If they remain in your home you risk spreading the infection all over again.

To help minimize this, some dog owners choose to limit their dog’s access around the home to one or two rooms that are easy to clean so they don’t spread the infection.

Consider keeping your dog in a room without carpet or upholstered furniture like the kitchen. Of course, you don’t have to do this; it just might make things easier for you in terms of decontamination.

Buying Guide – How to Pick the Best Ringworm Shampoo for Dogs

6. how to buy right ringworm shampoo

Having a good ringworm shampoo for dogs can be the difference between a short infection and a long-lasting one.

This is why picking the best product is so important.

In most instances, your vet might give you a few different recommendations that you can start with, but if they didn’t or you’re looking for more options, knowing what to look for in a good product can help you as you shop.

Look for dog-specific shampoos

First, you’ll want to look for a shampoo that is specifically made for dogs.

This is because you want a shampoo that is made to match a dog’s pH level so it doesn’t dry them out too much and cause other issues.

Avoid harmful ingredients

Certain ingredients like soaps, artificial fragrances, artificial dyes, and parabens should be avoided if possible.

These are ingredients that are known to trigger allergic reactions in dogs and cause irritation to overly sensitive animals.

If you know your dog is sensitive, test any shampoo you buy on them first before using it for a full bath.

Check if it can be used for active ringworm infection

Next, you should make sure that the shampoo you’re interested in is an antifungal made to treat fungal infections including ringworm.

You should also make sure that the shampoo says it can be used on dogs with active ringworm infections as some shampoos might say that you can’t use it if your dog has open lesions.

If you’re unsure, it’s best to do some research or talk to your vet or groomer and get their recommendation.

Unlike other dog shampoos, it’s hard to find natural antifungal shampoos that can fight ringworm, but if you really want to stay away from chemical products, look for something that is mostly natural or uses natural ingredients as the main component.

There are certain extracts and essential oils that have natural antifungal properties that can be useful in controlling a ringworm infection so you’re not completely at the mercy of chemically-based formulas.


How often should I bathe my dog with ringworm?

Ringworms tend to last for extended periods when mild or careless measures are taken to curb it. This will not only cause severe discomfort for your dog but shall pose a threat to you and your other pets.

While shopping for a ringworm dog shampoo the presence of certain compounds is extremely important. Some of them being Chlorhexidine, Miconazole and Ketoconazole. They help fight the remaining ringworm spores, treat the irritated skin left after ringworm and help kill the fungus in a period of few weeks.

Is diluted bleach all that is needed to cure ringworm on dogs?

Bleach is an extremely effective compound to help kill ringworm in dogs. However, you must ensure that you dilute it well before applying. 500ml or one pint of bleach must be added to a gallon or 4 liters of water and mixed well. The dilution must be in the ratio of 1:100. Diluted bleach helps kill the fungal spores and treat ringworm faster than any medication. However, a slight concentration of the bleach risks your pet’s life. Always consult your vet before applying bleach on your pet.

Can I use antifungal dog shampoo on other animals?
