Can Dogs Get Lice Like People Do?

Answered by Dr. Ivana Vukasinovic

Lice (Phthiraptera) are an order of insects, external parasites, secondary wingless representatives who live as obligate ectoparasites of mammals and birds.

Among mammals they don’t parasite only on Platypus and Echidna, some marsupials (rows Microbiotheria and Notoryctemorhpia), bats, whales, manatees and crustaceans.

There are two species of lice that infest dogs causing Canine Pediculosis:

  • Trichodectes canis (chewing louse)
  • Linognathus setosus (sucking louse)

Animals are infected by direct contact, or indirectly via infested objects. Diagnosis is made by finding (visual observing or scratching test) lice or their eggs in dogs hair. Louse is a flat insect that don’t fly or jump, it just crawls around; Lice have 3 pairs of short legs with large claws.

Untreated Pediculosis can cause a whole body infestation with symptoms such as: scratching, biting, itching, dry fur, hair loss and anemia. Some of these symptoms are very similar with the symptoms of flea infestation.

" Luckily lice is species specific. Because of this you can't get lice from your dog or give lice to your dog."~ Dr. Aron, veterinarian
