can animals cause head lice
There is a different species of louse for each species of animal. While dog lice are uncommon, Linognathus piliferus is the species most often found. The entire lifespan of a louse is lived on 1 host. Dog lice will not live on humans; nor will human lice live on dogs. Dog lice mate on the dog and attach their nits to the hairs of the dog. They hang on for life, for within hours they will die if not on the body of a host.
