Yes, dogs can get lice. Although lice infestations in dogs are uncommon and not often diagnosed, lice can be a nuisance for dogs. Dogs get lice mainly through direct contact with other infected dogs, contaminated grooming tools, overcrowded or unsanitary living conditions, and when they are ill or malnourished. Lice are species-specific, meaning dog lice only infest dogs and cannot be transmitted to humans, nor can dogs get lice from humans. Symptoms of lice infestation in dogs include itchiness, hair loss, redness, flaky or greasy skin, and visible lice or lice eggs stuck to the hair shaft. Lice live on the dog's hair shafts and feed on skin cells, dander, gland secretions, or blood, depending on the lice type. Treatment usually involves products to kill lice on the dog and in their environment, as well as care for any skin damage caused by the infestation. In summary, dogs can get lice, but these parasites only affect dogs and do not spread between species such as humans and dogs.
