What Does Ringworm Look Like on a Dog?
Ringworm appears in dogs as circular bald spots with red, scaly, or rough skin. The affected areas may feel itchy, swollen, or rough to the dog. It is most commonly found on the dog’s face, ears, tail, and paws, but it can spread throughout the dog’s body if left untreated.
Some dogs have fairly mild symptoms, while others may experience severe hair loss and discomfort. Early recognition and understanding what ringworm looks like in a dog is key to preventing the infection from progressing.
Signs and Symptoms of Ringworm in Dogs
The symptoms of ringworm in dogs can vary widely depending on the severity of the infection. Here are easy ways to identify it:
1. Visible lesions on the skin
Circular bald spots on the body, with scaly or rough skin
Redness and swelling in the affected areas
Sometimes, the skin may turn dark or brown
2. Hair loss (alopecia)
The hair falls out in a circular pattern
The dog’s fur becomes brittle and breaks easily
Uneven, patchy coat
3. Itchiness and discomfort
Many dogs itch excessively or even lick the area
In some cases, there may be mild irritation, while in others, there may be severe itching
4. Infection of nails and claws
The nails become brittle and discolored
Scaly skin around the claws
5. Spread of infection
If the dog is not treated on time, ringworm can spread to other parts of the body
It can also infect other dogs and humans
Causes of Ringworm in Dogs
Ringworm is a type of ringworm. The fungus is caused by dermatophytes, which thrive in warm and moist environments. Here are some common causes:
| Cause | Description |
|---|---|
| Direct Contact | Dogs can get infected by touching another infected animal. |
| Contaminated Surfaces | Fungi live on bedding, grooming tools, carpets, and furniture. |
| Weakened Immune System | Puppies, senior dogs, and those with weak immune systems are at higher risk. |
| Humid Environment | Warm and damp conditions encourage fungal growth. |
| Poor Hygiene | Dirty coats and lack of grooming can increase the risk of infection. |
How Do Vets Diagnose Ringworm in Dogs?
A vet may use the following methods to confirm a ringworm infection:
1. Woods lamp test
A special UV light (Woods lamp) is used to detect ringworm
The fungus glows in only 50% of cases, so additional testing may be needed
2. Fungal culture test
The most accurate test
This involves taking samples of the dog’s hair or skin and growing them in a laboratory to identify the fungus
3. Microscopic test
The vet examines the hair under a microscope to look for fungal spores
How to Treat Ringworm in Dogs?
If the dog is diagnosed with ringworm, it is very important to start treatment immediately. Vets usually recommend the following:
1. Topical antifungal treatment
Medicated shampoos (chlorhexidine or miconazole)
Apply antifungal creams and ointments to the affected area
2. Oral antifungal medications
These are prescribed for severe infections in dogs
Common medications: Itraconazole, Terbinafine, and Ketoconazole
3. Cleaning the environment
Disinfect all surfaces (bedding, furniture, and grooming tools)
Wash items with a bleach solution to kill fungal spores
4. Isolate infected pets
Keep the infected dog away from other animals and family members
Limit contact until treatment is complete
How Long Does It Take for Ringworm to Heal?
Recovery time depends on the severity of the infection and the dog’s immune system.
| Severity | Recovery Time |
|---|
| Mild case (topical treatment only) | 2-4 weeks |
| Moderate case (topical + oral meds) | 4-6 weeks |
| Severe case (widespread infection) | 6-12 weeks |
Dogs with strong immunity always recover faster. It is important to continue the correct treatment to completely eliminate the infection.
Can Humans Get Ringworm from Dogs?
Yes, of course. Ringworm is a zoonotic disease, which means it can be transmitted from dogs to humans. Young children, the elderly, and people with weakened immunity are at a higher risk than normal.
Prevention measures:
✅ Wear gloves when handling an infected dog
✅ Wash hands thoroughly after contact
✅ Always disinfect furniture, carpets, and pet items
✅ Avoid sharing dog bedding or grooming tools
How to Prevent Ringworm in Dogs?
The best way to prevent ringworm is to take good care of your dog.
Regular grooming and cleaning – keep your dog clean and dry
Disinfect the dog – clean bedding, brushes, and crates regularly
Avoid infected animals – be careful in dog parks and shelters
Boost immunity – have a balanced diet and regular veterinary checkups
Identify symptoms early – treat skin infections immediately
