Understanding Sarcoptic Mange
Sarcoptic mange, also known as scabies, is a highly contagious skin condition that affects dogs. It is caused by microscopic Sarcoptes mites, specifically Sarcoptes scabiei var cani. These mites can also infest other mammals such as foxes, coyotes, and wolves.
Definition and Causes
Sarcoptic mange is caused by the infestation of Sarcoptes scabiei mites on the skin of dogs. These mites are usually 0.2-0.4 millimeters in size and cannot be seen by the naked eye. The life cycle of these mites is complete within 3 weeks (PetMD). The mites burrow just beneath the skin’s surface, leading to intense itching and various skin-related symptoms. Sarcoptic mange is highly contagious, both between dogs and to humans. In humans, it causes temporary dermatitis with intensely itchy skin lesions that can last for several weeks.
To prevent the spread of sarcoptic mange, it’s important to isolate and treat affected dogs promptly. The mites can be transmitted through direct contact between dogs or contaminated environments such as kennels, grooming facilities, and dog parks (Cornell University College of Veterinary Medicine).
Symptoms and Clinical Signs
Dogs with sarcoptic mange experience intense itching due to an allergic reaction to the mite and its feces. Commonly affected areas include the margins of ears, elbows, and hocks. The symptoms of sarcoptic mange in dogs may include:
- Red, inflamed skin
- Crusty or scaly skin
- Hair loss
- Thickened and darkened skin
- Secondary bacterial skin infections
- Restlessness and discomfort
- Depressed mood
- Loss of appetite
- Weight loss (in severe cases)
If you suspect your dog may have sarcoptic mange, it’s important to consult with a veterinarian for an accurate diagnosis and appropriate treatment options. Treatment typically involves medication administration and may require follow-up care and monitoring to ensure the effective eradication of the mites and resolution of symptoms.

By understanding the definition, causes, and symptoms of sarcoptic mange, dog owners can recognize the signs of this condition and seek appropriate veterinary care to alleviate their dog’s discomfort and prevent the spread of the mites.
Diagnosis of Sarcoptic Mange
When it comes to diagnosing sarcoptic mange in dogs, a thorough evaluation is essential. Veterinarians employ various methods to confirm the presence of the Sarcoptes scabiei mites and differentiate sarcoptic mange from other skin conditions that cause itchiness. The two primary diagnostic approaches are skin scraping and microscopic examination, along with considering differential diagnoses.
Skin Scraping and Microscopic Examination
Skin scraping and microscopic examination are commonly used to diagnose sarcoptic mange in dogs. During this procedure, a veterinarian will gently scrape the dog’s skin to collect a sample. The sample is then examined under a microscope to identify the presence of Sarcoptes scabiei mites. However, it’s important to note that the mites may not always be visible due to their burrowing nature, which can make detection challenging (VCA Hospitals).
In certain cases, mites may not be found in the skin scraping sample, even if the dog is infected with sarcoptic mange. In such situations, a presumptive diagnosis can still be made based on clinical signs, such as intense itching, hair loss, and skin inflammation. Treatment may be initiated based on these signs and the response to therapy (Cornell University College of Veterinary Medicine).
Differential Diagnosis
Differential diagnosis is crucial in ruling out other skin conditions that can cause itchiness and may have similar clinical signs to sarcoptic mange. Some of the conditions that need to be considered include allergies, flea infestations, bacterial or fungal infections, and other types of mites.
The veterinarian will carefully evaluate the dog’s medical history, conduct a physical examination, and take into account the dog’s symptoms and clinical signs. This comprehensive assessment helps to differentiate sarcoptic mange from other potential causes of itching and skin problems.
By utilizing skin scraping and microscopic examination, along with considering differential diagnoses, veterinarians can accurately diagnose sarcoptic mange in dogs. Once a diagnosis is confirmed, appropriate treatment measures can be implemented.

Treatment Options for Sarcoptic Mange
When it comes to treating sarcoptic mange in dogs, a multi-step approach is necessary to effectively eliminate the mites and provide relief for your furry friend. Treatment options for sarcoptic mange include medication administration and follow-up care and monitoring.
Medication Administration
Various medications are available for treating sarcoptic mange in dogs. These medications can be administered through different methods, such as medicated baths, dips, injections, or oral medications. Commonly prescribed oral medications include milbemycin, afoxolaner, fluralaner, and sarolaner. These medications may come in the form of liquids, pills, or flavored chews and are typically given for multiple treatments. In Australia, NexGard® for Dogs and NexGard SPECTRA® for Dogs are popular choices for treating sarcoptic mange, along with other mite-related issues.
It’s important to follow your veterinarian’s instructions regarding the dosage and frequency of medication administration. Consistency is key to ensuring the effectiveness of the treatment. Additionally, it’s crucial to continue the treatment for the recommended duration, even if the symptoms improve. This helps to ensure that all mites and their life stages are eradicated.
Follow-up Care and Monitoring
After initiating the treatment, regular follow-up care and monitoring are essential. Most dogs with sarcoptic mange show improvement within two weeks of treatment, but full resolution may take up to 6-8 weeks. During this time, it’s important to closely observe your dog for any changes in symptoms and behavior.
Follow-up examinations with your veterinarian are crucial to assess the progress of the treatment and make any necessary adjustments. Your veterinarian may perform skin scrapings to check for the presence of mites and monitor the improvement of the condition. They may also prescribe additional medications, such as antibiotics for secondary bacterial infections or corticosteroids to reduce inflammation and itchiness (Cornell University College of Veterinary Medicine).
In addition to medication and veterinary visits, environmental management is an important aspect of follow-up care. Thoroughly clean and disinfect your dog’s bedding, toys, and living areas to prevent reinfestation. Regularly vacuuming and washing your dog’s belongings can help remove any remaining mites and eggs.
Remember, treating sarcoptic mange requires commitment and patience. Following the prescribed treatment plan, administering medications properly, and adhering to follow-up care and monitoring recommendations are essential for successful outcomes. It’s also important to treat all dogs in the household, even if they are not showing clinical signs, to prevent the spread of the mites.
Prevention and Control Measures
When it comes to managing and preventing sarcoptic mange in dogs, there are important measures that dog owners can take. By implementing these prevention and control strategies, you can help protect your dog and prevent the spread of mange to other pets or humans.
Environmental Disinfection
To prevent re-infestation and eliminate any mites that may be present in the environment, thorough environmental disinfection is key. While sarcoptic mange mites do not live in the environment for long periods of time, they can remain infective for up to 36 hours. Here are some steps you can take to effectively disinfect the environment:
- Wash and disinfect your dog’s bedding regularly. Discard or wash bedding in a diluted bleach solution to kill any mites that may be present (VCA Hospitals).
- Vacuum and clean your home thoroughly, paying extra attention to areas where your dog spends most of their time. Use a vacuum with a high-efficiency particulate air (HEPA) filter to trap any mites or eggs that may be present.
- Consider using a veterinary-recommended environmental spray that is specifically formulated to kill sarcoptic mange mites. Follow the instructions carefully to ensure proper use and effectiveness.
By implementing these environmental disinfection measures, you can reduce the risk of re-infestation and create a healthier living environment for your dog.
Zoonotic Transmission
Sarcoptic mange is a zoonotic condition, meaning it is transmissible from pets to humans. While the mite cannot complete its life cycle on humans, it can cause severe itching until it dies. To prevent the transmission of sarcoptic mange to humans, it is important to take precautions:
- Avoid direct contact with an infected dog, especially if they are actively scratching or displaying signs of mange.
- If you have been in contact with an infected dog or suspect exposure to sarcoptic mange, it is recommended to wash your hands thoroughly with soap and water. Additionally, consider changing and washing your clothes to minimize the risk of mites spreading to other areas of the body.
- If you develop symptoms such as intense itching and a rash, it is advisable to seek medical attention. Medical treatment may be necessary to alleviate the symptoms and address the underlying cause (VCA Hospitals).
By being aware of the zoonotic potential of sarcoptic mange and taking appropriate precautions, you can help protect yourself and your family members from potential exposure.
Remember, prevention is key when it comes to managing sarcoptic mange. Regular veterinary check-ups, proper grooming, and maintaining a clean living environment can go a long way in preventing and controlling this condition. For more information on the symptoms of sarcoptic mange in dogs and treatment options, consult with your veterinarian for guidance tailored to your dog’s specific needs.
Sarcoptic Mange in Dogs: Case Studies
To gain a deeper understanding of sarcoptic mange in dogs, let’s explore two specific case studies that shed light on the condition’s impact on older dogs and the successful treatment approaches.
