Mange in Dogs: Symptoms, Causes, and Treatment

Mange is a common but serious skin condition that can cause intense itching, hair loss, and discomfort in dogs. This condition is caused by microscopic mites that burrow into a dog’s skin, leading to irritation, inflammation, and secondary infections if left untreated. While mange is more common in stray dogs, puppies, and those with weakened immune systems, any dog can be affected.

Understanding the signs, causes, and treatment options for mange is essential for restoring your dog’s skin health and preventing the spread of the condition. By taking a proactive approach to treatment and nutrition, you can help your dog recover faster and maintain a healthy, itch-free coat.

Key Takeaways

• Mange is a skin condition caused by microscopic mites that lead to itching, hair loss, and skin irritation. It can spread through direct contact with infected animals or contaminated surfaces.
• Early detection and treatment are essential. Veterinary care, medicated treatments, and improved nutrition can help dogs recover and prevent mange from worsening.

A nutrient-rich diet supports skin and coat health. Feeding your dog Spot & Tango’s Fresh Dog Food provides essential vitamins, antioxidants, and healthy fats that promote healing and strengthen the skin barrier.

What Is Mange in Dogs?

Mange is a parasitic skin disease caused by microscopic mites that infest a dog’s skin and hair follicles. These mites can cause mild to severe itching, redness, crusty skin, and hair loss. While some types of mites naturally live on a dog’s skin in small numbers, mange occurs when the population grows uncontrollably, leading to inflammation, discomfort, and infections.

How Do Dogs Get Mange?

Mange is typically spread through direct contact with an infected animal or contaminated surfaces, such as bedding, grooming tools, or outdoor environments. Certain factors can increase a dog’s risk of developing mange, including:

• A weakened immune system (common in puppies, senior dogs, and sick dogs).
• Poor nutrition that affects skin health and the body’s ability to fight infections.
• Living in crowded conditions, such as shelters or kennels.

While mange is highly treatable, early detection is key to preventing it from worsening or spreading to other pets.

Diet plays a crucial role in supporting a dog’s immune system and skin health. Feeding your dog a high-quality, whole-food diet like Spot & Tango’s Fresh Dog Food can help strengthen their skin barrier, reduce inflammation, and support overall recovery.

Types of Mange in Dogs

There are two primary types of mange that affect dogs: sarcoptic mange and demodectic mange. While both are caused by mites, they differ in how they spread, the severity of symptoms, and the best approach to treatment.

1. Sarcoptic Mange (Canine Scabies)

Sarcoptic mange, commonly referred to as canine scabies, is highly contagious and can spread to other animals and even humans. It is caused by the Sarcoptes scabiei mite, which burrows into the dog’s skin, leading to severe itching and irritation.

Symptoms of Sarcoptic Mange:

• Intense itching that worsens over time.
• Red, inflamed skin with crusty patches.
• Hair loss, especially around the ears, elbows, legs, and belly.
• Thickened or scaly skin in advanced cases.
• Restlessness and discomfort due to constant scratching.

Sarcoptic mange is highly contagious, often spreading through direct contact with infected dogs or shared bedding, collars, and grooming tools. Because this type of mange can spread to humans—causing mild skin irritation or itching—it’s crucial to seek veterinary treatment immediately if you suspect an infection.

2. Demodectic Mange (Demodex)

Unlike sarcoptic mange, demodectic mange is not contagious between dogs or humans. It is caused by Demodex mites, which naturally live on a dog’s skin but multiply uncontrollably in dogs with weakened immune systems. This type of mange is more common in:

• Puppies (whose immune systems are still developing).
• Senior dogs or those with underlying health conditions.
• Dogs experiencing stress or poor nutrition.

Symptoms of Demodectic Mange:

• Localized hair loss, usually around the face, eyes, and paws.
• Mild to moderate itching (less intense than sarcoptic mange).
• Red, flaky, or scaly skin in affected areas.
• Oily or smelly skin in severe cases.

While some mild cases of demodectic mange may clear up on their own, more severe cases require medicated treatment and support for the immune system and skin health.

What Does Mange Look Like on a Dog?

Mange can look different depending on the type and severity of the infection, but the most common visual signs include:

• Patchy hair loss, often starting around the face, ears, or legs.
• Scaly, red, or inflamed skin due to irritation from mites.
• Crusty sores or scabs, especially in cases of sarcoptic mange.
• Thickened or hardened skin in chronic or untreated cases.
• Oily or foul-smelling skin, common in severe demodectic mange.

How to Tell Mange Apart from Other Skin Conditions

Because mange symptoms overlap with other skin conditions (such as allergies or fungal infections), it’s important to consult a veterinarian for a proper diagnosis. A vet may perform:

• Skin scrapings to detect mites under a microscope.
• Blood tests to rule out immune-related conditions.
• Skin cultures or allergy tests to eliminate other possible causes of irritation.

The earlier mange is identified, the easier and faster it is to treat—preventing severe discomfort, infections, and further spread to other pets.

Mange Treatment: How to Help Your Dog Recover

Treating mange requires a combination of veterinary care, medicated treatments, and proper nutrition to restore your dog’s skin health and eliminate mites. The best treatment approach depends on the type and severity of mange your dog has.

1. Veterinary Diagnosis & Prescription Treatments

Before starting treatment, your veterinarian will confirm the type of mange through a skin scraping test. Once diagnosed, your vet may prescribe:

• Medicated Shampoos & Dips – Specially formulated shampoos and lime sulfur dips help kill mites and soothe irritated skin.
• Oral & Topical Medications – Prescription medications like isoxazoline-based flea and tick preventatives (NexGard, Bravecto, Simparica) are highly effective at eliminating mange mites.
• Antibiotics or Antifungal Medications – If secondary infections develop due to excessive scratching, your vet may prescribe medications to prevent complications.
• Anti-Inflammatory Treatments – To reduce swelling, redness, and discomfort, steroids or antihistamines may be recommended in severe cases.

2. Home Care & Natural Support for Mange Recovery

While prescription treatments are necessary to eliminate mites, supporting your dog’s overall skin health at home can speed up recovery and prevent future flare-ups.

Improve Hygiene & Reduce Mite Exposure

• Wash your dog’s bedding, collars, and toys frequently to eliminate lingering mites.
• Vacuum regularly to remove mites from carpets and furniture.
• Bathe your dog with vet-approved soothing shampoos to reduce skin irritation.

Boost Skin & Coat Health Through Nutrition

Proper nutrition plays a major role in skin recovery. A high-quality, whole-food diet provides the essential nutrients needed to repair damaged skin, reduce inflammation, and strengthen immunity.

Mange Prevention: How to Protect Your Dog

While mange is treatable, prevention is always better than cure. Keeping your dog’s skin and immune system strong, along with regular hygiene and parasite control, can greatly reduce the risk of mange.

1. Regular Flea & Mite Prevention

Many prescription flea and tick preventatives also protect against mange-causing mites. Speak with your veterinarian about monthly preventatives like:

• NexGard, Bravecto, or Simparica – These oral medications effectively kill mange-causing mites before they cause an infestation.
• Topical treatments – Some spot-on flea preventatives also provide mite protection.

Preventative care is especially important if your dog regularly visits dog parks, boarding facilities, or interacts with stray or rescue animals.

2. Maintain Good Hygiene & Grooming

• Wash your dog’s bedding, collars, and toys regularly to remove potential mites.
• Bathe your dog with a gentle, moisturizing shampoo to keep their skin clean and healthy.
• Brush your dog’s coat frequently to remove dead skin cells and improve circulation.

3. Strengthen Your Dog’s Immune System with Proper Nutrition

A strong immune system helps your dog naturally resist infections, including mite overgrowth. Feeding a nutrient-rich, whole-food diet supports skin health and overall immunity.

Spot & Tango’s Fresh Dog Food is an excellent choice for mange prevention because it includes:

• Wholesome proteins that maintain skin strength.
• Omega-3 and Omega-6 fatty acids to support a healthy skin barrier.

When to See a Vet for Mange

If your dog shows early signs of mange, a veterinary exam is crucial for diagnosis and treatment. Mange can worsen quickly, leading to painful skin infections and significant hair loss if left untreated.

Signs That Warrant a Vet Visit:

• Persistent Scratching & Hair Loss – If your dog is losing patches of hair and scratching excessively, mites could be the cause.
• Crusty, Red, or Inflamed Skin – Skin that appears thickened, scaly, or infected may need immediate veterinary attention.
• Foul Odor or Open Sores – Bacterial or fungal infections often develop in severe cases of mange, requiring antibiotics or medicated treatments.
• Multiple Pets in the Household Show Symptoms – If you notice itching or hair loss in more than one pet, mange could be spreading between animals.

What to Expect at the Vet

A veterinarian will:

• Perform a skin scraping test to confirm the presence of mites.
• Prescribe appropriate oral or topical medications.
• Provide a treatment plan that includes medicated baths and supportive care.

Catching mange early leads to faster recovery and prevents unnecessary discomfort for your dog. If symptoms persist, consult your vet as soon as possible.
