What Causes Mange in Dogs?

Mange is a skin condition in dogs that is caused by microscopic mites. These mites burrow into the skin and cause inflammation, hair loss, and skin lesions. It is a common problem that can affect dogs of all breeds, ages, and sizes. It can also be contagious to other dogs.

This article will discuss the different types of mange, the causes of each type, and the symptoms you can look out for. It will also touch upon the treatment options available for mange and how to prevent it.

What is Mange?

Mange is a skin disease that is caused by tiny parasites called mites. These mites burrow into the skin of dogs and cause inflammation, redness, itching, and hair loss. There are two main types of mange: sarcoptic mange and demodectic mange.

Sarcoptic Mange

Sarcoptic mange, also known as scabies, is caused by the Sarcoptes scabiei mite. This type of mange is highly contagious and can be spread from dog to dog or even from dog to human.

Causes of Sarcoptic Mange

Sarcoptic mange is caused by the Sarcoptes scabiei mite. This mite burrows into the skin of dogs and lays eggs. The eggs hatch into larvae that burrow further into the skin, causing inflammation and itching. The mites can spread from dog to dog through direct contact, or through shared bedding, collars, or other objects.

Symptoms of Sarcoptic Mange

The symptoms of sarcoptic mange can vary depending on the severity of the infection. However, some common symptoms include:

  • Intense itching
  • Hair loss
  • Redness and inflammation of the skin
  • Crusty scabs
  • Small, raised bumps on the skin

Sarcoptic mange can affect any part of the body, but it is most commonly seen on the ears, head, legs, and abdomen.

Demodectic Mange

Demodectic mange, also known as “red mange,” is caused by the Demodex canis mite. This type of mange is not as contagious as sarcoptic mange and is often associated with a weakened immune system.

Causes of Demodectic Mange

Demodectic mites are naturally found on the skin of most dogs. However, they usually do not cause any problems. Demodectic mange occurs when the immune system is compromised, allowing the mites to multiply and cause skin lesions. Factors that can weaken the immune system include:

  • Puppyhood: Puppies are more susceptible to demodectic mange because their immune systems are not fully developed.
  • Stress: Stress can weaken the immune system and make dogs more vulnerable to demodectic mange.
  • Illness: Dogs with underlying medical conditions, such as diabetes, are more susceptible to demodectic mange.
  • Poor Nutrition: A poor diet can also weaken the immune system and increase the risk of demodectic mange.

Symptoms of Demodectic Mange

The symptoms of demodectic mange can vary depending on the severity of the infection. However, some common symptoms include:

  • Hair loss
  • Redness and inflammation of the skin
  • Scaly skin
  • Blackheads or pustules

Demodectic mange typically affects the face, legs, and feet. However, in severe cases, it can spread to the entire body.

Diagnosis of Mange

If you suspect your dog may have mange, it is important to see a veterinarian for diagnosis. A veterinarian can examine your dog’s skin and take a skin scraping to identify the mites under a microscope.

Treatment of Mange

The treatment for mange will depend on the type of mange.

Sarcoptic Mange Treatment

Sarcoptic mange is typically treated with a combination of medications, including:

  • Medicated shampoos: These shampoos help kill the mites and reduce inflammation.
  • Oral medications: Oral medications, such as ivermectin, are used to kill the mites and prevent them from reproducing.
  • Injectable medications: Injectable medications are also used to kill the mites and prevent them from reproducing.

Demodectic Mange Treatment

Demodectic mange is typically treated with:

  • Medicated shampoos: Medicated shampoos help kill the mites and reduce inflammation.
  • Oral medications: Oral medications, such as ivermectin or milbemycin, are used to kill the mites and prevent them from reproducing.
  • Immune-suppressing drugs: In severe cases of demodectic mange, immune-suppressing drugs may be used to help the dog’s immune system fight off the mites.

Prevention of Mange

There are a number of things you can do to help prevent your dog from getting mange:

  • Regularly groom your dog: Regular grooming helps remove loose hair and dirt, which can harbor mites.
  • Use a flea and tick preventative: Flea and tick preventatives can also help prevent mange, as the mites that cause mange are closely related to fleas and ticks.
  • Keep your dog’s immune system strong: A strong immune system can help prevent your dog from getting mange. This can be done by feeding your dog a healthy diet, providing regular exercise, and keeping your dog up-to-date on vaccinations.
  • Avoid contact with other dogs that have mange: If you know that a dog has mange, avoid contact with it to prevent your dog from getting infected.

Conclusion

Mange is a common skin condition in dogs that can cause a lot of discomfort. While it can be challenging to treat, it is important to seek veterinary attention for your dog if you suspect mange. With prompt treatment and proper prevention measures, you can help keep your dog healthy and free from mange.

FAQ

What is mange?

Mange is a skin condition in dogs caused by tiny parasites called mites. These mites burrow into the dog’s skin, causing irritation, inflammation, and hair loss. There are two main types of mange: sarcoptic mange and demodectic mange. Sarcoptic mange is highly contagious and can spread to other dogs and even humans. Demodectic mange, on the other hand, is caused by mites that are naturally present in low numbers on all dogs. However, certain factors can cause these mites to multiply and trigger an infestation.

While both types of mange are caused by mites, they differ in their characteristics, symptoms, and treatment approaches. Sarcoptic mange is more commonly seen in younger dogs and is highly contagious, while demodectic mange is less common and can be associated with certain breeds and underlying health conditions. Understanding the specific type of mange your dog has is crucial for selecting the right treatment plan.

What are the symptoms of mange?

The symptoms of mange can vary depending on the type of mange and the severity of the infestation. However, some common signs include:

  • Intense itching: This can lead to excessive scratching, licking, and chewing at the affected areas.
  • Hair loss: The mites’ burrowing activity can damage hair follicles, resulting in patches of hair loss, especially around the ears, face, and paws.
  • Redness and inflammation: The skin may become red, inflamed, and scaly.
  • Crusting and scabbing: In severe cases, the skin may develop crusts and scabs.
  • Skin thickening: Over time, the skin may thicken and become leathery.

These symptoms can be quite distressing for dogs, and it’s important to seek veterinary attention as soon as you notice them.

Is mange contagious to humans?

While both types of mange can affect dogs, only sarcoptic mange (also known as scabies) is contagious to humans. This means that a person can catch it from an infected dog. However, demodectic mange is not contagious to humans.

If you suspect your dog has mange, it’s essential to keep them away from other dogs and to seek veterinary advice. You should also wash your hands thoroughly after handling your dog, and avoid close contact with their skin.

How is mange diagnosed?

A veterinarian can diagnose mange based on a thorough physical examination and a skin scraping test. During the examination, the veterinarian will look for characteristic skin lesions and examine the dog’s coat for hair loss and other signs of mange.

The skin scraping test involves collecting a small sample of skin and examining it under a microscope for mites. If mites are present, the veterinarian can confirm the diagnosis and determine the specific type of mange.

How is mange treated?

Treatment for mange usually involves medicated shampoos, dips, or oral medications. The specific treatment plan will depend on the type of mange, the severity of the infestation, and your dog’s overall health.

For sarcoptic mange, treatment typically involves topical medications that kill the mites. In some cases, oral medications may also be prescribed. Treatment for demodectic mange is more complex and may require longer-term medication.

Can mange be prevented?

Preventing mange in dogs involves a combination of good hygiene practices, regular parasite control, and a healthy diet. It’s essential to wash your dog’s bedding and grooming tools regularly to prevent the spread of mites.

Regular flea and tick prevention can help prevent mites from infesting your dog. A healthy diet and immune system can also make your dog less susceptible to mange. Consult your veterinarian for specific recommendations on preventing mange in your dog.

What is the prognosis for dogs with mange?

The prognosis for dogs with mange is generally good, especially if the condition is diagnosed and treated early. However, the severity of the infestation and the underlying health of the dog can influence the outcome.

With prompt treatment, most dogs with mange will fully recover and live healthy lives. However, some dogs may experience recurring infestations or develop complications such as bacterial infections. If you notice any signs of mange in your dog, it’s crucial to seek veterinary attention immediately. Early intervention can help prevent severe complications and ensure a positive outcome for your dog.
