Understanding Demodectic Mange
Demodectic mange, also known as demodicosis or red mange, is a skin condition in dogs caused by an overgrowth of Demodex mites that typically inhabit the hair follicles. These mites are a normal part of the skin flora and are usually harmless. However, in certain situations, such as in dogs with weakened immune systems, these mites can multiply rapidly, leading to the development of demodectic mange.
Demodectic Mange Overview
Demodectic mange is the most common form of mange in dogs, and it primarily affects young dogs under 12 to 18 months of age. Puppies with immature or weakened immune systems are more susceptible to the overgrowth of Demodex mites. Additionally, adult dogs with underlying illnesses, malnutrition, or certain medications that suppress the immune system are also at higher risk for developing demodectic mange. The mites reside in the hair follicles, leading to hair loss and other skin-related symptoms.
Causes of Demodectic Mange
The primary cause of demodectic mange in dogs is an overgrowth of Demodex mites. These mites are typically present on the skin and benefit from their host without causing harm. However, in dogs with weakened immune systems, the mites can multiply and disrupt the normal balance. Puppies with immature immune systems or adult dogs with underlying illnesses that depress their immune systems are more prone to the overgrowth of Demodex mites, leading to the development of demodectic mange.
Some of the factors that can contribute to weakened or compromised immune systems in dogs include:
- Genetic predisposition: Certain breeds, such as American Staffordshire Terriers, Boxers, and Bulldogs, may have a higher genetic susceptibility to demodectic mange.
- Stress: Environmental stressors, changes in routine, or other sources of stress can weaken a dog’s immune system, making them more susceptible to demodectic mange.
- Illness or disease: Dogs with underlying health conditions, such as hormonal imbalances, endocrine disorders, or malnutrition, may have compromised immune systems, increasing the risk of demodectic mange.
- Medications: Certain medications, such as corticosteroids or other immunosuppressive drugs, can suppress the immune system and contribute to the development of demodectic mange.

Symptoms of Demodectic Mange
Demodectic mange, also known as demodicosis, is a skin condition in dogs that is caused by an overgrowth of Demodex mites. Recognizing the symptoms of demodectic mange is important for early detection and treatment. Common symptoms include hair loss and alopecia, skin scaling and irritation, and the presence of bumps and skin thickening.
Hair Loss and Alopecia
One of the primary signs of demodectic mange is hair loss, also known as alopecia. The hair loss typically occurs in localized areas and can vary in severity. It may appear as patchy bald spots or thinning of the coat. Hair loss due to demodectic mange is usually not accompanied by itching, unlike other types of mange. If you notice any unusual hair loss in your dog, it is recommended to consult a veterinarian for a thorough examination.
Skin Scaling and Irritation
In addition to hair loss, dogs with demodectic mange may exhibit skin scaling and irritation. This can manifest as dry, flaky skin or even redness and inflammation. The affected areas may appear rough or scaly to the touch. Skin scaling and irritation are often localized to specific regions of the body, such as the face, neck, or paws. If you notice any changes in your dog’s skin texture or condition, it is important to seek veterinary attention for a proper diagnosis.
Bumps and Skin Thickening
Another symptom of demodectic mange is the presence of bumps and thickening of the skin. These bumps, known as papules, can vary in size and may be accompanied by pigmentation changes. In some cases, the skin may become visibly thicker or more leathery in texture. The severity of these symptoms can vary depending on the extent of the mite infestation and any secondary skin infections that may be present.
It is important to note that the symptoms of demodectic mange can vary from dog to dog. Some dogs may only exhibit mild symptoms, while others may experience more severe manifestations. If you suspect that your dog may have demodectic mange, it is crucial to consult with a veterinarian for proper diagnosis and guidance.

Diagnosing Demodectic Mange
When it comes to diagnosing demodectic mange in dogs, there are several methods that veterinarians employ to accurately identify the condition. These diagnostic techniques include skin scraping and examination, cytology and PCR testing, and skin biopsy for severe cases.
Skin Scraping and Examination
Skin scraping and examination is a common method used to diagnose demodectic mange in dogs. During this procedure, the veterinarian will gently scrape the surface of the dog’s skin using a scalpel or a specialized tool. The collected skin sample is then examined under a microscope to detect the presence of Demodex mites. The veterinarian will look for larger than normal numbers of these mites to confirm the diagnosis of demodectic mange.
Cytology and PCR Testing
Cytology, which involves collecting samples of skin cells or fluids, is another diagnostic method used for demodectic mange. The samples are examined under a microscope to identify the presence of Demodex mites and assess the severity of the infestation. Additionally, polymerase chain reaction (PCR) testing can be performed to detect the DNA of the mites. It is important to note that PCR testing may yield false negative results, so it is often used in conjunction with other diagnostic techniques to increase accuracy (PetMD).
Skin Biopsy for Severe Cases
In severe cases of demodectic mange, where the condition is generalized and affects a large area of the dog’s body, a skin biopsy may be necessary. A skin biopsy involves the removal of a small piece of tissue from the affected area, which is then examined under a microscope. This procedure is performed to confirm the diagnosis and rule out other potential skin conditions that may have similar symptoms. Skin biopsies are typically reserved for severe or atypical cases of demodectic mange (VCA Hospitals).
By utilizing these diagnostic methods, veterinarians can accurately identify demodectic mange in dogs. It is important to consult a veterinarian if you suspect your dog may be affected by this condition. Early diagnosis and prompt treatment can help manage the symptoms and improve the overall well-being of your furry friend.

Treatment Options for Demodectic Mange
When it comes to treating demodectic mange in dogs, the approach varies based on the severity of the infection. Treatment options range from localized infections to generalized infections, and may involve miticidal therapy and medications.
Localized Infections Treatment
In the case of localized demodectic mange, where the condition is confined to a small area of the dog’s body, treatment may not always be necessary. In many instances, localized infections resolve spontaneously within 1-2 months.
However, if treatment is deemed necessary, topical medications are commonly used. These medications can include medicated shampoos that contain benzoyl peroxide, which help open and flush hair follicles, allowing for more efficient penetration of the treatment. Topical ointments and creams may also be prescribed to target the affected areas.
Generalized Infections Treatment
Generalized demodectic mange, which affects larger areas of the dog’s body or even the entire body, requires more aggressive treatment. Miticidal therapy is often necessary to eliminate the Demodex mites responsible for the infection.
There are various miticidal medications available for treating generalized demodectic mange. These medications may include oral or topical treatments. Commonly used medications include ivermectin, milbemycin oxime, doramectin, amitraz, fluralaner, afoxolaner, sarolaner, and lotilaner. However, it’s important to note that dogs with MDR1 mutations should not receive ivermectin (PetMD).
The specific medication and dosage will depend on the individual dog’s condition and the veterinarian’s recommendation. It’s crucial to follow the veterinarian’s instructions carefully and complete the full course of treatment to ensure the eradication of the mites and prevent a recurrence.
Miticidal Therapy and Medications
Miticidal therapy, as mentioned earlier, involves the use of medications that specifically target and eliminate the Demodex mites. These medications work by disrupting the mites’ ability to reproduce and survive.
Some of the commonly used miticidal medications include:
- Ivermectin
- Milbemycin oxime
- Doramectin
- Amitraz
- Fluralaner
- Afoxolaner
- Sarolaner
- Lotilaner
The choice of medication will depend on various factors, including the severity of the infection and the dog’s overall health. It’s important to consult with a veterinarian to determine the most appropriate miticidal therapy for your dog.
While undergoing treatment for demodectic mange, it’s essential to monitor your dog’s progress and follow up with regular check-ups. This allows the veterinarian to assess the response to treatment and make any necessary adjustments if required.
Remember, successful treatment of demodectic mange requires patience and consistency. Adhering to the prescribed treatment plan, maintaining good hygiene practices, and providing a supportive environment for your dog’s recovery will greatly increase the likelihood of a positive outcome.
Demodectic Mange in Puppies
Puppies are particularly susceptible to demodectic mange, a skin condition caused by an overgrowth of Demodex mites. In this section, we will explore the presentation of demodectic mange in puppies and discuss severe cases.
Presentation in Puppies
Demodectic mange lesions in puppies often begin around the face and head area due to close contact with the mother during feeding. However, they can appear anywhere on the body. Puppies with demodectic mange may exhibit the following symptoms:
- Hairless patches: Puppies may develop localized hair loss in small patches around the lips, eyes, and legs (WagWalking). These patches may be accompanied by mild itching or discomfort.
- Redness and inflammation: The affected areas may show signs of redness and inflammation, indicating an immune response to the mite infestation.
- Mild scaling: Some puppies may exhibit mild scaling or flakiness of the skin in the affected areas.
If you notice any of these symptoms in your puppy, it’s important to seek veterinary care for a proper diagnosis and treatment plan. Early detection and intervention can help prevent the condition from progressing to more severe forms.
Severe Cases in Puppies
In rare cases, demodectic mange in puppies can progress to a generalized form, leading to more severe symptoms and complications. Severe generalized demodectic mange may present with:
- Pain and discomfort: Puppies with severe mange may experience pain and discomfort due to the intense inflammation and irritation of the skin.
- Lethargy: The mite infestation and associated symptoms can cause puppies to become lethargic and less active.
- Fever: Some puppies may develop a fever as a result of the immune response to the mite infestation.
- Draining wounds: In severe cases, the skin may develop draining wounds, which can be painful and may become infected.
- Skin swelling: The affected areas may become swollen and exhibit pronounced inflammation.
- Ear infections: If the mites invade the ear canals, puppies may develop ear infections, leading to additional discomfort and irritation (PetMD).
Severe cases of demodectic mange in puppies require immediate veterinary attention. A veterinarian will be able to diagnose the condition through various methods, such as skin scraping, hair plucking, cytology, and in some cases, skin biopsy. Treatment options, including localized or generalized infection treatment and miticidal therapy, can then be determined based on the severity of the condition (PetMD, treatment for demodectic mange).
If you suspect demodectic mange in your puppy, consult with your veterinarian for an accurate diagnosis and appropriate treatment plan. Timely intervention can help alleviate symptoms and ensure the well-being of your furry companion.
Demodectic Mange in Adult Dogs
While demodectic mange is commonly associated with puppies, adult dogs can also develop this condition. There are specific factors and variations that can occur when demodectic mange affects adult dogs.
Underlying Conditions in Adult Dogs
Adult dogs that develop demodectic mange often have underlying health issues or weakened immune systems, which create an environment conducive to the overgrowth of Demodex mites. These underlying conditions can include hormonal imbalances, allergies, immune system disorders, or other chronic illnesses. It’s important to address these underlying conditions to effectively manage demodectic mange in adult dogs.
Generalized Demodecosis in Adult Dogs
In some cases, demodectic mange in adult dogs may present as generalized demodecosis. Unlike localized demodectic mange, which is characterized by a few patches of hair loss, generalized demodecosis involves a more widespread and severe spread of the disease across the skin (VCA Hospitals).
Symptoms of generalized demodecosis can include extensive hair loss, skin inflammation, redness, scaling, and crusting. Adult dogs with this condition may also experience secondary bacterial infections due to the compromised state of their skin. Prompt diagnosis and treatment are crucial to managing and controlling generalized demodecosis in adult dogs.
If you suspect demodectic mange in your adult dog, it’s essential to seek veterinary care for an accurate diagnosis and appropriate treatment. Your veterinarian may perform skin scrapings to identify the presence of Demodex mites or may recommend a skin biopsy for a definitive diagnosis (VCA Hospitals).
Treatment for demodectic mange in adult dogs often involves a combination of localized or generalized treatment approaches, depending on the severity of the condition. These treatment options may include topical medications, oral medications, or a combination of both. Your veterinarian will determine the most suitable treatment plan based on your dog’s specific needs and the underlying conditions present.
It’s important to note that treatment for demodectic mange in adult dogs may take time and require regular follow-ups with the veterinarian. Additionally, addressing any underlying health issues and providing appropriate supportive care will help improve the overall well-being of your adult dog.
