Mange!! Dr. Dan talks about Demodex and Sarcoptic Mange.

Hi Everyone! My name is Dan, and today I am talking about mange in the dog. Demodex in Dogs (also called Demodectic Mange or Red Mange) is a skin condition caused by an overgrowth of microscopic mites called Demodex canis that live in the hair follicles and oil glands of dogs' skin. What is Demodex? Normal in small numbers: Most dogs have some Demodex mites as part of their skin microbiome. Becomes a problem when the immune system can’t keep the mite population in check, leading to mange. Types of Demodectic Mange Localized Demodicosis: Usually affects puppies. Small, patchy hair loss (commonly on face and front legs). Often resolves on its own. Generalized Demodicosis: Can affect adult dogs or become severe in puppies. Widespread hair loss, scaly skin, secondary infections, odor. More serious, often needing long-term treatment. May be associated with underlying immune suppression or genetic predisposition. Diagnosis: Skin scraping under a microscope (mites are usually easy to find). Trichogram (plucking hairs and looking for mites). Biopsy in rare cases. Treatment: Topical medications: e.g., imidacloprid/moxidectin (Advantage Multi), amitraz dips. Oral medications: Isoxazolines (NexGard, Bravecto, Simparica) — now often first-line. Antibiotics if secondary skin infections occur. Supportive care: medicated shampoos, skin supplements. Sarcoptic Mange in Dogs (also known as Scabies) is a highly contagious and intensely itchy skin disease caused by the Sarcoptes scabiei mite, a microscopic parasite that burrows into the skin. What Causes It: Sarcoptes scabiei var. canis, a parasitic mite. Mites burrow into the skin, causing severe irritation and inflammation. Highly contagious to other dogs and can infect humans (zoonotic). Signs and Symptoms: Extreme itching (often worse at night). Hair loss (especially on ears, elbows, chest, abdomen). Red, scaly, crusty skin. Thickened skin in chronic cases. Secondary bacterial infections from scratching. Diagnosis: Skin scrapings (but mites are notoriously hard to find). Pinnal-pedal reflex (rubbing the ear causes scratching with hind leg). Response to treatment often confirms the diagnosis. Fecal exam may find mites from swallowed skin debris. Treatment Options: Isoxazolines (NexGard, Bravecto, Simparica) — highly effective and often first choice now, Selamectin (Revolution) or moxidectin/imidacloprid (Advantage Multi), Lime sulfur dips (older but still used sometimes), Antibiotics if secondary infections occur, Anti-itch medications (steroids or oclacitinib/Apoquel) short-term for relief.
