Mange is a skin condition that affects dogs, caused by microscopic mites that burrow into the skin, leading to itching, hair loss, and inflammation. This condition can vary in severity, from mild irritation to more serious, widespread symptoms that cause significant discomfort and even health risks.
As a pet owner, it is essential to be able to recognize the early signs of mange in dogs and understand the effective solutions for treatment. In this article, we will delve into the causes, symptoms, types of mange, and available treatments to help you manage this condition effectively.
How to Spot Mange in Dogs: Early Signs and Effective Solutions
What is Mange?
Mange in dogs is an infectious skin disease caused by parasitic mites. These mites are typically microscopic and are classified into two main types: sarcoptic mange and demodectic mange. Both types involve different types of mites and have varying causes, symptoms, and treatments.
Sarcoptic Mange (Scabies): Caused by the Sarcoptes scabiei mite, this form of mange is highly contagious, spreading easily from one dog to another. It often causes intense itching, hair loss, and skin inflammation.
Demodectic Mange (Demodicosis): This form is caused by the Demodex mite, which is normally found in small numbers on a dog’s skin. However, when the dog’s immune system is compromised, these mites can multiply, leading to mange. Demodectic mange is typically not contagious and is most common in puppies, older dogs, or dogs with weakened immune systems.
Both types of mange lead to similar symptoms, but the causes and treatments differ significantly.
How to Spot Mange in Dogs: Early Signs
Recognizing mange early is crucial for effective treatment. The symptoms of mange can be subtle at first but often escalate quickly, leading to discomfort for the dog. Below are the key signs of mange in dogs to watch for:
1. Intense Itching and Scratching
One of the earliest and most noticeable signs of mange is excessive itching. This occurs as the mites burrow into the skin, causing irritation and inflammation. Dogs with mange may scratch, bite, or lick at the affected areas more frequently than usual. If your dog suddenly starts itching intensely, especially in specific areas, this could be a sign of mange.
2. Hair Loss (Alopecia)
Mites attack the hair follicles, leading to hair loss. In cases of sarcoptic mange, hair loss usually starts at the ears, face, and elbows. With demodectic mange, the hair loss typically begins around the eyes, muzzle, or paws. Over time, bald patches may appear on the dog’s body, and these areas may become inflamed or scaly.
3. Red, Inflamed Skin
As the mites cause irritation and infection, the skin becomes red, inflamed, and sore. Dogs with mange may develop raised, crusty scabs or pustules on their skin. The affected skin may also appear thickened or leathery as the condition progresses.
4. Crusts and Scabs
The skin affected by mange may begin to form crusts and scabs, which are a result of scratching and irritation. These scabs can cause further discomfort for the dog and may lead to secondary bacterial infections if left untreated. This is especially common in dogs with sarcoptic mange.
5. Foul Odor
In severe cases, mange can lead to bacterial infections, which produce a foul odor. If your dog’s skin smells unusually bad, it could be a sign of infection, which is often associated with untreated mange.
6. Thickened Skin and Darkening
As the infection progresses, the skin in the affected areas may become thickened, wrinkled, and darkened (a condition called hyperpigmentation). This symptom is more common in chronic cases of mange.
7. Redness Around Eyes or Paws (For Demodectic Mange)
In the case of demodectic mange, the symptoms are often localized, with the skin around the eyes, ears, and paws becoming red and inflamed. These areas may develop small pustules or sores, which can be painful for your dog.
Types of Mange in Dogs
As mentioned earlier, there are two primary types of mange that affect dogs: sarcoptic mange and demodectic mange. Understanding the differences between the two will help you identify which type your dog might have.
Sarcoptic Mange (Scabies)
Cause: Caused by the Sarcoptes scabiei mite, which is highly contagious.
Transmission: This type of mange can spread easily through direct contact with an infected dog or through contaminated bedding, grooming tools, or other objects.
Symptoms: Intense itching, hair loss, red, crusty skin, and scabs.
Contagiousness: Sarcoptic mange is highly contagious and can also spread to humans, although it typically doesn’t cause the same symptoms in people.
Treatment: Sarcoptic mange is treated with medicated baths, topical treatments, or oral medications prescribed by a veterinarian. In some cases, antibiotics or steroids may be required to manage secondary infections.
Demodectic Mange (Demodicosis)
Cause: Caused by the Demodex mite, which is present in small numbers on most dogs’ skin but can become problematic if the immune system is weakened.
Transmission: This type of mange is not contagious and is often linked to the dog’s immune system function.
Symptoms: Hair loss, red or inflamed skin, scabs, and crusts.
Contagiousness: Demodectic mange is not contagious and cannot be transmitted to other dogs or humans.
Treatment: Treatment for demodectic mange involves addressing the underlying immune deficiency, using oral medications like ivermectin or amitraz, and possibly medicated shampoos.

How to Treat Mange in Dogs
If you suspect your dog has mange, it is essential to visit a veterinarian for proper diagnosis and treatment. Treating mange early is crucial to avoid severe skin infections and discomfort for your dog. Here are the most common treatments for mange:
1. Medications
Depending on the type of mange, your veterinarian may prescribe the following treatments:
Topical Treatments: These treatments include shampoos, sprays, or ointments that kill the mites on contact. For sarcoptic mange, topical treatments may be prescribed alongside oral medications.
Oral Medications: Oral medications such as ivermectin, milbemycin, or spinosad can help to kill the mites and reduce inflammation.
Steroids: In cases where inflammation is severe, corticosteroids may be prescribed to help manage the itching and redness.
Antibiotics: Secondary bacterial infections are common with mange, so your vet may prescribe antibiotics to treat any infections that have developed due to scratching and open sores.
2. Regular Baths and Grooming
Bathing your dog with a medicated shampoo designed to kill mites can help manage mange and soothe irritated skin. Regular baths, along with gentle grooming, can remove crusts and scabs while promoting healing. It is important to use a shampoo recommended by your veterinarian to ensure its effectiveness.
3. Supportive Care for Immune System Support (For Demodectic Mange)
For dogs with demodectic mange, supporting their immune system may be necessary. This can involve administering immune-boosting supplements, such as omega-3 fatty acids, and ensuring your dog receives a balanced, high-quality diet. In severe cases, treatment may also involve managing any underlying health conditions, such as hormonal imbalances or cancer, that are compromising the dog’s immune function.
4. Isolate Infected Dogs (For Sarcoptic Mange)
If your dog has sarcoptic mange, it’s important to isolate them from other pets to prevent the spread of the mites. Infected dogs should also be kept away from human family members, as the condition can be transmitted to people, though the mites do not survive long on human skin.
Preventing Mange in Dogs
While mange can be difficult to prevent entirely, there are a few steps you can take to minimize the risk of your dog developing the condition:
Regular Vet Check-ups: Routine veterinary exams can help detect mange or other skin conditions early on, allowing for prompt treatment.
Maintain a Healthy Immune System: Ensure your dog is on a balanced diet and receives proper care to keep their immune system strong.
Prevent Contact with Infected Dogs: If you know a dog with mange, keep your dog away from them to prevent the mites from spreading.
Keep Bedding and Living Areas Clean: Regularly clean your dog’s bedding, toys, and grooming tools to prevent the spread of mites.
