What is the sucking louse species that infests dogs?

Explanation:
Sucking lice feed on the host’s blood with piercing mouthparts, so they cause irritation and skin problems by a blood-sucking mechanism. The dog-infesting species that fits this pattern is Linognathus setosus, a true sucking louse that targets dogs. It’s different from Trichodectes canis, which is a chewing louse that bites and feeds on skin debris rather than blood, and from Pthirus pubis and Pediculus humanus, which are human lice. So, for a sucking louse species that infests dogs, Linognathus setosus is the correct choice.
