Dog lice are nasty parasites that cling to a dog’s skin or fur, sucking blood or feeding on skin debris. Unlike fleas and ticks, lice are species-specific—they affect only dogs and are not commonly transmitted to humans or other pets. The discomfort and health risks they pose make early recognition essential for prompt treatment.
Signs of Dog Lice
Classic signs of infestation include:
-
Intense itching and scratching
-
Visible dead lice or lice eggs on the dog’s hair
-
Hair loss, primarily around the ears, neck, shoulders, groin, and rectum
-
Excessive scratching, which may lead to small wounds and skin redness
-
In severe cases, anemia due to blood loss
Types of Dog Lice & Transmission
The two main types of lice that infest dogs are:
-
Chewing Louse (Trichodectes canis) – Feeds on skin debris and spreads through direct contact with infested dogs or contaminated objects like combs, brushes, bedding, and the environment.
-
Sucking Louse (Linognathus setosus) – Though less common, these lice are more troublesome as they feed on blood. They spread similarly through direct contact or shared spaces.
Diagnosing Dog Lice
A veterinarian typically diagnoses lice by:
-
Conducting a physical examination of the dog
-
Using a magnifying glass to look for lice or nits
-
Confirming the presence of lice to determine the best treatment plan
Treating Dog Lice
A veterinarian should always oversee treatment. Management may include:
-
Medicated shampoos and topical treatments – Designed to kill lice
-
Regular grooming – Helps remove nits and adult lice
-
Cleaning and replacing bedding, collars, and grooming tools – Prevents reinfestation
