Mange in Dogs: Essential Facts and Treatments

“Mange” is a painful skin disease caused by microscopic parasitic mites that can infest dogs and other animals. It manifests as irritation, hair loss, and intense itching, requiring prompt care to ensure your pet’s comfort and health.

What is Mange in Dogs?

Mange is caused by tiny mites burrowing into a dog’s skin or hair follicles. The two main types affecting dogs are demodectic mange and sarcoptic mange. Each type is caused by different mite species and has distinct characteristics. Understanding these differences helps in effective treatment and prevention.

Demodectic Mange

Demodectic mange, often called red mange, is caused by the Demodex canis mite. These mites normally live harmlessly on many dogs, but if a dog’s immune system weakens—due to illness or age—the mites multiply excessively. This leads to localized or generalised hair loss and skin inflammation.

Typically, demodectic mange is not contagious between dogs except from a mother to her puppies during nursing. Puppies may develop mild cases which often resolve naturally as their immune systems mature. However, adult dogs with compromised immunity can experience more severe outbreaks requiring veterinary intervention.

Sarcoptic Mange

Sarcoptic mange—sometimes called canine scabies—is caused by the burrowing Sarcoptes scabiei mite. This form is highly contagious, spreading from dog to dog and potentially to other animals and humans. It causes intense itching, scabs, crusts, and hair loss. Due to its contagious nature, dogs with sarcoptic mange should be isolated, and their environment thoroughly cleaned.

How is Mange Diagnosed?

If mange is suspected, a veterinarian will perform a skin scraping test, examining samples under a microscope to detect mites. Sarcoptic mites may sometimes be difficult to find, so vets might rely on clinical signs and response to treatment for diagnosis. Early diagnosis is vital to manage the disease effectively and prevent spread.

Treatment Options for Mange in Dogs

Both forms of mange require veterinary-supervised treatment. Options include:

• Medicated shampoos or sulfurated lime dips applied bi-weekly, which soothe skin and kill mites
• Topical treatments such as ivermectin, selamectin, or permethrin applied to the skin to eradicate parasites
• Oral or injectable antiparasitic medications as prescribed by the vet
• Antibiotics to manage secondary bacterial infections caused by scratching

Prompt treatment not only alleviates your dog’s discomfort but also reduces the risk of transmission to other pets or humans.

Preventing Mange in Your Dog

Maintaining your dog’s overall health with a balanced diet, regular vet check-ups, and good hygiene helps keep mange at bay. Because sarcoptic mange is so contagious, avoid contact with infected animals and wildlife—such as foxes known to carry mange in the UK. If your dog develops symptoms, seek veterinary advice promptly to ensure quick and effective treatment.

Responsible Pet Ownership and Mange

Recognising signs of mange early and acting responsibly by following veterinary advice and isolating affected dogs protects your pet and community animals. Ethical breeding practices also reduce the risk of inherited immune issues that may predispose dogs to demodectic mange.

If you are looking to find a puppy, choose only reputable breeders who prioritise health and conduct appropriate health screening. This reduces the risk of mange and other diseases.

Understanding mange and acting swiftly ensures your dog recovers fully and stays healthy. If you suspect mange, contact your vet for diagnosis and discuss the best treatment plan to keep your beloved pet comfortable and safe.
