Walking Dandruff In Dogs – Causes, Symptoms, & Treatment

Walking Dandruff In Dogs

What Is Walking Dandruff In Dogs?

Walking Dandruff (cheyletiellosis) is an uncommon but highly contagious skin parasite of dogs caused by Cheyletiella yasguri (Cheyletiella sp.) mites. These large, whitish mites crawl across skin and fur giving an appearance of dandruff moving around with excessive scaling (but they don’t jump like fleas) and so it is also called walking dandruff.

Usually, they hide into your dog’s skin and cause excessive scaling (scurf, dandruff), which gives the fur or coat a mealy or powdery look, particularly over the back side dorsal midline. Another familiar skin condition in dogs ‘mange’ is also caused by these mites. 'Walking dandruff’ affects the dogs from other infected pets at groomers/animal shelters/kennels/breeders or other areas where several dogs come in contact with one another.

Although Cheyletiella species mites are species-specific, they do transport easily from one host species to another and cross-infect humans as well. The Cheyletiella prevalence is worldwide and seems to be predominantly common in countries, where standard flea control programs with long-term antiparasitic products are not in practice.

'Walking dandruff’ infection is self-restricting, as humans are inadvertent hosts. Earlier, this condition is considered to be synonymous with the “itchy red bump” disease, a pruritic papular disorder of indecisive histogenesis that was initially reported in Florida. But now it is found to be papular dermatitis. Complete recovery from cheyletiellosis occurs within 2- 4 weeks after the pet is diagnosed, and properly treated and the environment has been cleared of mites.

How To Prevent Walking Dandruff In Dogs?

  • Consult with the pet experts about the best tick collars, oral medications, and spot-on treatments for the dog
  • Outdoor dogs wandering in the lush forested pathways, tick-infested wooded areas, and feeding areas should be restricted
  • After a walk outdoors, don’t forget to frisk your dog for any fleas or ticks – in the belly, chest, neck, ears, toes, and back
  • A commercial ear flush or an apple cider vinegar mixed in the required amount of water and flush monthly
  • For controlling mites and other parasites, there are medicated shampoos for pets specifically
  • Hotspots for mites are bedding, pillows, carpets, curtains, mattresses, and upholstered furniture in your house. If you suspect a considerable infestation, rinse the garments in warm water (+125°) at least monthly once to kill dust mites
  • Use special air filters that would effectively trap mites, dust, and skin cells such as Portable air purifiers, HEPA air purifiers, and ULPA Air Purifiers, and in the Heating, ventilation, and air conditioning system
  • When the household dust mites have gone berserk, consult with experts for pesticides and commercial powders for dust mite control
