Understanding Demodectic Mange
Demodectic mange is a skin condition in dogs caused by microscopic Demodex mites that naturally inhabit a dog’s hair follicles. These mites are usually harmless, but they can cause skin disease if the dog’s immune system is unable to control their population, particularly in young or malnourished dogs (NexGard). Demodectic mange, also known as red mange, is the most common form of mange in dogs.
Demodectic Mange Overview
Demodectic mange is primarily caused by two species of mites: Demodex canis and Demodex injai. These cigar-shaped mites have eight short legs and live in the hair follicles of dogs. While they are a normal inhabitant of a dog’s skin, an overgrowth of these mites can lead to skin infections and mange.
Causes of Demodectic Mange
Demodectic mange can occur in dogs of any age, but it is most commonly seen in dogs under 12 to 18 months old, as well as in older dogs with weakened immune systems. The exact cause of the overgrowth of Demodex mites is not fully understood, but it is believed to be related to the dog’s immune system and overall health.
In young dogs, especially puppies, the immune system is still developing, making them more susceptible to demodectic mange. Puppies can acquire the mites from their mother while suckling milk, as their immune system is not yet strong enough to control the mite population (PetMD). However, exposure of a healthy dog to another dog with demodectic mange is not dangerous, as it requires a depressed immune system for the disease to develop (PetMD).
Other factors that can contribute to the development of demodectic mange include underlying health conditions that weaken the immune system, such as malnutrition or certain diseases. Dogs with a compromised immune system are more susceptible to the overgrowth of Demodex mites, leading to the manifestation of mange symptoms.

Symptoms and Diagnosis
Identifying and diagnosing demodectic mange in dogs is crucial for effective treatment and management. This section will discuss the signs and symptoms of demodectic mange as well as the diagnostic procedures used by veterinarians.
Signs of Demodectic Mange
Demodectic mange in dogs is caused by microscopic Demodex mites that live in the dog’s hair follicles. These mites are a normal inhabitant of a dog’s skin but can cause skin disease if the immune system is unable to control the mite population, especially in young or malnourished dogs (NexGard). The symptoms of demodectic mange can vary depending on secondary skin infections or the localization of lesions.
Common signs of demodectic mange in dogs include:
- Alopecia (hair loss)
- Skin scaling
- Bumps on the skin (papules)
- Pigmentation changes in the skin
- Thickening of the skin
- Itchiness
It’s important to note that the severity and extent of these symptoms can vary depending on the individual dog and the stage of the disease. If you suspect your dog may have demodectic mange, it is recommended to consult with a veterinarian for a proper diagnosis and appropriate treatment plan.

Diagnostic Procedures
To diagnose demodectic mange in dogs, veterinarians employ several diagnostic procedures. These procedures help confirm the presence of Demodex mites and assess the extent of the infestation. The most common diagnostic methods include:
-
Skin scraping: During a skin scraping, a veterinarian will gently scrape the affected area of the dog’s skin to collect a sample. The sample is then examined under a microscope to identify the presence of Demodex mites.
-
Hair plucking: In some cases, hair plucking may be performed to collect hair follicles for examination. The hair roots are examined for the presence of mites.
-
Cytology: Cytology involves taking a sample of the skin or discharge from lesions and examining it under a microscope. This helps identify any secondary bacterial or fungal infections that may be present alongside demodectic mange.
In severe or generalized cases of demodectic mange, additional diagnostic tests such as polymerase chain reaction (PCR) testing or skin biopsy may be necessary to confirm the diagnosis and determine the most appropriate treatment.
If you suspect your dog has demodectic mange, it is crucial to consult with a veterinarian for an accurate diagnosis. They will be able to recommend the most suitable treatment plan based on the severity and extent of the mange infestation.

Treatment Options
When it comes to demodex mange in dogs, prompt and appropriate treatment is essential to manage the condition effectively. The treatment options for demodectic mange can vary depending on the severity and extent of the infestation. In this section, we will explore two main treatment options: localized demodectic mange and generalized demodectic mange.
Localized Demodectic Mange
Not all cases of demodectic mange require treatment. In localized infections, which are limited to a specific area, the condition may resolve spontaneously within 1-2 months (PetMD). However, if treatment is necessary, it typically involves topical medications.
Special shampoos containing benzoyl peroxide are often recommended to allow dip and topical treatments to penetrate more efficiently. Topical medications may include miticidal treatments to eliminate the mites. It’s important to follow your veterinarian’s instructions regarding the frequency and duration of treatment to ensure optimal results.
Generalized Demodectic Mange
Generalized demodectic mange, which affects larger areas of the dog’s body, often requires more aggressive treatment. Medications such as miticidal treatments (oral or topical) may be prescribed to target the mites (VCA Hospitals). Some commonly used medications include ivermectin, milbemycin, doramectin, moxidectin + imidacloprid, and fluralaner.
It’s important to note that while ivermectin is sometimes used off-label for treating generalized demodectic mange, it should only be administered under the guidance of a veterinarian due to potential side effects if not properly administered. Other treatments may include topical antifungal and antibacterial medications to address secondary infections, as well as oral antibiotics to prevent or treat any bacterial complications.
The specific treatment plan for generalized demodectic mange will depend on the individual dog’s condition, response to treatment, and any underlying health issues. Regular check-ups with your veterinarian are crucial to monitor progress and make any necessary adjustments to the treatment regimen.
While treating demodectic mange is generally successful when done promptly and appropriately, the management of underlying health conditions is crucial to prevent complications and ensure the best possible outcome. By working closely with your veterinarian and following their recommended treatment plan, you can help your dog overcome demodectic mange and restore their skin health.
Prevention and Management
When it comes to preventing demodectic mange in dogs, there are some measures that dog owners can take to minimize the risk of their furry companions developing this condition. Additionally, for dogs that already have demodectic mange, effective management strategies can help control the symptoms and improve their overall well-being.
Preventing Demodectic Mange
Demodectic mange is not contagious to other animals or humans. The mites that cause demodectic mange are transmitted to puppies from their mother during the first few days of life. It’s important to note that exposure of a healthy dog to one with demodectic mange is not dangerous unless the immune system is depressed (VCA Hospitals). To prevent the spread of demodectic mange, it is crucial to avoid breeding dogs with demodectic mange, and the parents of affected dogs should not be bred again.
Managing Chronic Cases
For dogs with chronic or recurrent demodectic mange, effective management is essential. The treatment for demodectic mange can vary depending on the severity of the condition. Mild cases may only require topical medications, while more generalized cases may require a combination of topical and oral medications.
Treatment options for demodectic mange may include medications such as moxidectin + imidacloprid, fluralaner, doramectin, or off-label use of ivermectin. It is important to consult with a veterinarian to determine the most appropriate treatment plan for your dog.
In addition to medication, managing chronic cases of demodectic mange involves addressing underlying health conditions and supporting the dog’s immune system. Regular veterinary check-ups, proper nutrition, and a healthy lifestyle can help strengthen the immune system and improve the dog’s ability to fight off mite infestations.
Furthermore, maintaining good hygiene practices, such as regular bathing with medicated shampoos or prescribed topical treatments, can help manage the symptoms and reduce mite populations on the skin. It is crucial to follow the veterinarian’s instructions regarding the frequency and application of these treatments.
By implementing preventive measures and effectively managing chronic cases, dog owners can help minimize the impact of demodectic mange on their furry companions. Regular veterinary care, proper hygiene, and a supportive environment can contribute to the well-being and comfort of dogs affected by this condition.

Demodectic Mange in Puppies
Demodectic mange, also known as demodicosis, is a skin condition that commonly affects puppies. Understanding the transmission of demodectic mange and the development of the immune system in puppies is crucial in managing and preventing the condition.
Transmission from Mother
Demodectic mange is most often transmitted from the mother dog to her puppies during the first few days of life. This transmission occurs while the puppies are suckling milk from their mother. The mites responsible for demodectic mange are species-specific, meaning they can only survive on the skin of dogs and are not contagious to other animals or humans (Atlantic Coast Veterinary Specialists). The transmission of demodectic mange from mother to puppy is facilitated by the pup’s immature immune system, which is still developing during the early stages of life.
Immune System Development
The development of a puppy’s immune system plays a significant role in the development and management of demodectic mange. Puppies are born with an immature immune system, making them more susceptible to infestation by Demodex mites. As the immune system matures, it gains the ability to regulate the mite population on the skin, preventing the overgrowth that leads to demodectic mange.
During the first few months of a puppy’s life, the immune system undergoes crucial development. Adequate nutrition, proper healthcare, and a stress-free environment contribute to the healthy development of the immune system. Ensuring that puppies receive a balanced diet and regular veterinary care can help support their immune system as they grow.
It’s important to note that exposure of a healthy dog to one with demodectic mange is not dangerous unless the immune system is depressed. Proper management and prevention of demodectic mange in puppies involve supporting their immune system development through appropriate nutrition, regular veterinary check-ups, and minimizing stressors that may weaken their immune response.
Understanding the transmission of demodectic mange from mother to puppy and the development of the immune system in puppies is essential in addressing and preventing the condition. By providing a healthy and supportive environment for puppies, dog owners can aid in the proper development of their immune system, reducing the risk of demodectic mange.

Prognosis and Treatment Success
When it comes to demodex mange in dogs, the prognosis and treatment success can vary depending on the severity of the condition and the overall health of the dog. Understanding the success rate of treatment and managing any underlying health conditions are crucial aspects of effectively addressing demodectic mange.
Success Rate of Treatment
Treating demodectic mange in dogs is generally successful when done promptly and appropriately. The success rate of treatment can be high, especially for localized cases. With proper treatment, the mites can be eliminated, and hair regrowth can occur within a few months.
Topical medications are often the first line of treatment for localized cases. These medications may include medicated shampoos, dips, or spot-on treatments. In mild cases, these topical treatments alone may be sufficient to control the mange and promote healing.
For more generalized cases of demodectic mange, more aggressive treatment approaches may be necessary. Oral medications, such as moxidectin + imidacloprid, fluralaner, and doramectin, are commonly used to target the mites systemically. These medications help eliminate the mites from the dog’s body and prevent their recurrence.
It’s important to note that ivermectin is an off-label treatment option for demodectic mange in dogs, and it should only be used under the guidance of a veterinarian. While it can be effective, there is a potential for side effects, especially in certain dog breeds that are more sensitive to the medication.
Managing Underlying Health Conditions
In some cases, dogs with demodectic mange may have underlying health conditions that complicate the treatment process. These conditions can include immune system disorders, hormonal imbalances, or secondary infections. Managing these underlying health conditions is essential to ensure successful treatment and prevent severe consequences.
If an underlying health condition is identified, it’s important to address it alongside the demodectic mange treatment. This may involve additional medications or treatments specific to the underlying condition. By managing these medical conditions, the overall health and immune function of the dog can be improved, which aids in combating the mange and preventing relapses.
Regular veterinary check-ups and follow-up appointments are crucial to monitor the progress of treatment and adjust the approach as needed. Your veterinarian can guide you on the appropriate treatment plan and provide the necessary support and guidance throughout the process.
Remember, demodectic mange in puppies can be a result of transmission from the mother, and their immune system is still developing. Early detection and treatment are important to prevent the condition from worsening. If you suspect demodectic mange in your puppy, consult with a veterinarian for proper diagnosis and treatment options (VCA Hospitals).
By understanding the success rate of treatment and managing any underlying health conditions, you can increase the likelihood of successfully addressing demodectic mange in dogs. With proper veterinary care and a comprehensive treatment plan, your furry friend can regain their health and experience relief from this condition.
