Clinical Effects

Epidemiology

Lifecycle

  • See lifecycle diagram Lifecycle Demodex canis - diagram :
    • Eggs.
    • Larva.
    • Nymph.
    • Adult.

Transmission

  • Direct transmission from bitch to puppies in first 2-3 days of life.
  • Requires very close contact when mites pushed up from follicles in bitch's skin transfer to the puppy's skin and enter the hair follicles.
  • Transfer occurs at sites of closest contact when suckling; accounts for the predominance of initial lesions in pups in the perioral and periocular areas of the head and the dorsal aspects of the distal limbs, particularly the forelimbs.

Control

Control via animal

  • Treatment of disease associated with these parasites is detailed in Skin: demodectic mange Skin: demodectic mange.
