  • 3 instars as moults.

Transmission

  • Direct contact with the coat of infected canids.
  • Infested environment.

Pathological effects

  • Infestations can be subclinical with minimal pathological change in the skin.
  • Dermatitis with associated histopathological changes can occur at bite sites.
  • Heavy infestations can lead to anemia with fatal cases reported.

Other Host Effects

  • Adults feed on skin and blood of hosts through biting/chewing.

Control

Control via animal

  • Ectoparasite treatment.
  • Physical removal of adults and eggs by combing.
