Cheyletiella Mange

Cheyletiellosis — the 3rd type of mange!

An infestation of C. yasguri parasitic mites is responsible for Cheyletiella mange, Cheyletiellosis, or as it’s commonly known, walking dandruff. It got the nickname walking dandruff because of the way the mite maneuvers around beneath the keratin layer, pushing up scales of skin so that they seem to be moving, and leaving a dusty surface of skin scales on the surface of the hair.

Once relatively unknown, these contagious, non-burrowing, non-seasonal, carnivorous parasites are considered underdiagnosed epidemic. Alice M. Jeromin, DVM, recently stated, “In our practice, we actually see more cases of Cheyletiella mites “walking dandruff” than fleas!”

The Cause

The reason dogs get walking dandruff is that they were in the wrong place at the wrong time. There’s nothing you did or didn’t do to put your dog in this predicament. These mites are aggressive travelers and hungry opportunists who thought your dog looked delicious.

Cheyletiella are transmitted by direct contact with an infested 2-or 4-legged host or by indirect contact if the victim has visited an area where a host has deposited mites or eggs.

The mites lay in wait off of a host for up to 10 days while seeking a new host. During this time they are little tourists that stay busy infesting other territories and laying eggs.

Cheyletiella Mange

Please note that within each type of mange, every dog reacts a little differently with its own set of signs and symptoms. Your dog may exhibit all, some, or none of the following indicators. The level of symptom severity is also all over the lot.

If you suspect Cheyletiella, the primary symptoms associated with it include excessive scratching, skin scales, underlying skin irritation, and minor, patchy hair loss. The skin sometimes has small, red raised areas where the mites have bitten and the coat, usually unkempt looking, is scattered with flakes that look like dandruff but are in fact small, pale yellow Cheyletiella mites. You may be able to see the mites on close inspection or watch in terror as skin flakes (dandruff) mysteriously move on the skin’s surface.

If you’re unsure you may want to visit our Symptom Checker page. It can help you narrow down which type your dog has.

Good to know:

  • Preferred area of infestation is the back
  • Skin irritation & hair loss are typically minimal
  • Young animals have an increased risk of infection due to their immature immune systems
  • Carnivorous, eats keratin debris and tissue fluids


Other conditions with similar symptoms can make it hard to get a confirmed diagnosis. Some of those health issues are dandruff, flea-allergy reactions, infestation by mites other than Cheyletiella, allergic reactions due to food sensitivity, diabetes, and skin allergies that are particular to your dog. If those are not ruled out your dog may well end up being treated for the wrong disorder.

Diagnosing Cheyletiella can be tricky because it depends on finding mites or eggs during the exam and that’s not always possible. Clinical diagnoses are made by close examination of biopsied tissue, skin scrapings, flakes and/or dandruff caught on sticky tape, or anything collected with a fine comb or small vacuum cleaner for the presence of the mites or their eggs. Fecal examination and fecal float tests may also turn up mites and eggs swallowed during self-grooming. However, none of these methods are foolproof, and mites may not be discovered even when they are present.

Home diagnostics include reviewing symptomatology and history, close skin examination, tape testing, combings, and if you’re feeling invincible, fecal examination. You are looking for mites, eggs, or moving flakes, and a strong magnifying glass or a microscope will help you make a better diagnosis. To do a tape test, use a 6-inch length of clear sticky tape and press the adhesive side repeatedly to the dog’s coat. Mites on the surface can get stuck on the tape. If you attempt fecal examination, dig around and look for hookworm-like eggs in the feces.

Negative results happen in 15 percent of dogs and 58 percent of cats with Cheyletiella. Be careful about when you conduct your tests. If the animal has just been groomed or bathed the number of mites will be reduced. Be sure to check other pets in the household too.

Good to know:

  • Pale, slightly yellowish in color, chunky, fat-waisted mite
  • May be visible with the naked eye
  • A dead giveaway is if you see dandruff or flakes move across your pet’s skin
  • Symptoms usually develop 3–5 weeks after exposure
  • A negative test result is not reliable diagnosis
  • Other animals and/or people itch (20–80% contract it after exposure)

Your Treatment Options

Good to know:

  • Length of treatment following Mite Avenge treatment plan is 3 weeks
  • Length of treatment with chemicals is indefinite
  • All household rabbits and dogs must be treated. Do not use Mite Avenge on cats!
  • Household decontamination is required
  • Herding breeds like Collies, Shetland Sheepdogs, Old English Sheepdogs, and others are known to carry the MDR1 gene mutation should never be treated with chemicals

Traditional treatments are chemical insecticides that are licensed for other purposes besides mange. They all contain neurotoxins that systemically spread through the body, turning every cell into a poison bomb. Overall they fail about a third of the time, have consistently high incidences of harmful side effects and recurrence is common because decontamination is not addressed. Side effects can range from digestive upset to wobbly legs to seizures and on rare occasions, death. Some owners have success and are comfortable with chemical treatments, some don’t know they have options, and a growing number want nothing to do with them.

Today, more and more pet owners demand safer alternatives and seek a natural route, but many pet owners are not aware that there are other options.
