Mites and Mange in Dogs and Cats: What They Are, How to Treat

Sarcoptic, Demodex and Cheyletiella mites — what each one looks like, why steroids make sarcoptic mange worse, and the natural three-step treatment.

Mites and mange are widely misunderstood and often misdiagnosed — sometimes with steroids that make things dramatically worse. Here’s what each kind of mite actually does, and how to treat the infestation naturally.

What are mites?

Mites are microscopic creatures that resemble miniature spiders. Several species can attack cats and dogs.

Sarcoptic mites (scabies)

Sarcoptic mites are members of the family Sarcoptidae. They burrow under the skin — and they are nasty creatures. Infestations are called scabies and they are highly contagious.

Symptoms include:

  • Intense itching
  • Reddening of the skin
  • Thinning of the hair (alopecia)
  • Development of crusts and scabs
  • Secondary bacterial infections in the inflamed, irritated skin

Sarcoptic mites prefer skin with little hair, so they are most numerous on the ears, elbows, abdomen and hocks. As the disease spreads, hair is lost and eventually the mites occupy large areas of skin.

Demodex mites

Demodicidae mites live in or near the hair follicles of mammals — including humans. Small numbers are present in normal pets and cause no problems. In stressful situations, however, they proliferate, and large numbers inhabit the skin and hair follicles.

The good news: Demodex mites can easily be seen on a skin scraping under the microscope. The less good news: generalised demodicosis is serious and often difficult to treat. Large areas of the body may be affected, often with secondary bacterial infection. The skin becomes red, crusty, warm, full of pustules, may bleed easily, and develops a strong rancid odour.

Cheyletiella — “walking dandruff”

Cheyletiella mites look like tiny spiders under a magnifying glass. They live on the surface of the skin and are often called “walking dandruff” — because close inspection reveals that what look like little flakes of dry skin are actually moving about.

Why mange is so often misdiagnosed

Sarcoptic mite infestation is frequently misdiagnosed as allergic dermatitis — even by very competent and experienced veterinarians. The mites burrow so deep into the skin that they’re virtually undetectable on a skin scraping.

The result is predictable and damaging: many dogs are treated with cortisone or prednisone for a supposed allergic dermatitis, when in fact Sarcoptic mites are the underlying cause of the itching and inflamed skin. The unnecessary steroids suppress the immune system, the mites spread further, and the condition gets steadily worse.

If your dog has been given a “cortisone shot for the itching” and isn’t improving, mange is worth ruling out properly before the next round of steroids.

The Dermagic protocol

Dermagic products stop the infections associated with parasitic infestations and kill certain parasites outright. The system works in three steps.

Step 1 — Deep-cleansing bath

Before any treatment, give your dog a thorough cleansing with one of the organic Shampoo Bars, specially formulated for deep cleansing of sensitive skin. Bathe weekly or every two weeks while undergoing treatment — not more often than that.

Options across the range:

  • Flea Bar with diatomaceous earth — for flea-related problems
  • Skin Rescue Bar (Lemongrass and Neem Oil) — award-winning, for problem skin
  • Peppermint and Tea Tree Oil Shampoo Bar — for minty fresh deep cleansing
  • Rosemary and Lavender Shampoo Bar — stimulates hair follicles, calming
  • Chamomile and Sage — refresher

Step 2 — Skin Rescue Lotion

Apply DERMagic Skin Rescue Lotion for fast and effective relief from skin irritations, hot spots, scaly skin, flea allergies, dermatitis and dry skin conditions. Massage well into problem areas, then cover the dog with a t-shirt to protect the skin and keep the lotion in place.

Twice daily for the first week, then once daily for another week.

For more serious cases — including Black Skin Disease (Alopecia X) — extend the protocol accordingly.

Step 3 — Hot Spot Salve

For raw and irritated hot spots, use DERMagic Hot Spot Salve, applied daily to affected areas until no longer needed. The salve also treats minor wounds, insect bites, localised allergic reactions, and any itchy or inflamed patch.

Frequently asked questions

What are mites?
Mites are microscopic creatures that look like miniature spiders. Several species attack cats and dogs — Sarcoptic mites (which burrow under the skin), Demodex mites (which live in or near the hair follicles), and Cheyletiella mites (which sit on the surface and look like ‘walking dandruff’).
What's the difference between Sarcoptic and Demodex mange?
Sarcoptic mange — scabies — is highly contagious, causes intense itching, hair thinning, crusts and scabs, and is hard to detect because the mites burrow deep into the skin. Demodex mites are present in small numbers in normal pets and only cause problems when they proliferate under stress; they’re easy to spot on a skin scraping but generalised demodicosis is often serious and harder to treat.
Why is mange often misdiagnosed as allergic dermatitis?
Sarcoptic mites burrow so deep that they’re virtually undetectable on a skin scraping. Many vets — even competent and experienced ones — diagnose allergic dermatitis based on symptoms (itching, inflamed skin) and prescribe cortisone or prednisone. The steroids suppress the immune system, the mites spread further, and the condition gets worse.
How is Cheyletiella different?
Cheyletiella mites are larger and visible under a magnifying glass. They live on the surface of the skin and look like flakes of dandruff that are moving — hence the nickname ‘walking dandruff’. They’re contagious and treatable.
How does Dermagic treat mites and mange?
A three-step protocol: deep-cleansing bath with an organic shampoo bar, twice-daily application of Skin Rescue Lotion to affected areas (covered by a t-shirt to keep it on), and Hot Spot Salve dabbed onto raw or irritated patches. The natural antimicrobials kill mites topically without suppressing the immune system.
