Can Dogs Get Lice?
Yes, dogs can get lice, but the good news is dog lice are species-specific - they will not infest humans or cats. They cause itching, scratching, a rough or matted coat, and hair loss, and heavy infestations can even cause anaemia in puppies. Lice spread by direct contact or shared grooming tools, and they are treated with vet-recommended parasite products, repeated after 7 to 10 days to catch newly hatched lice.
Yes - dogs can get lice, though it’s far less common than fleas, especially in dogs on regular parasite prevention. The reassuring part: dog lice are species-specific, so they won’t set up home on you or your cat.
Will I catch lice from my dog?
No. Lice are highly host-specific - dog lice live on dogs, human lice live on humans. You might occasionally get a bite if you handle an infested dog, but you can’t get a lice infestation from your dog, and your dog can’t catch yours. The same goes for cats.
Signs of lice on a dog
- Persistent itching, scratching and biting at the skin
- A dry, rough or matted coat
- Hair loss, often around the ears, neck, shoulders, groin and rear
- Tiny lice or pale eggs (nits) glued to the hair shafts - visible on close inspection, especially with a magnifier
- Small sores or skin infections from scratching
- In severe cases, or in puppies and small dogs, anaemia from blood-feeding lice
Unlike fast-moving fleas, lice move slowly and their nits stick firmly to the hair, which helps tell them apart.
How dogs catch lice
Lice spread through direct contact with an infested dog, or via shared grooming tools, bedding and collars. Places where dogs mix - shelters, kennels, grooming salons, dog parks - are the usual settings. Neglected or unwell dogs are more prone.
Treatment
- See your vet to confirm it’s lice and get the right product - many vet-recommended flea/parasite treatments (spot-ons such as fipronil or selamectin, or certain shampoos) also kill lice.
- Repeat the treatment after about 7–10 days to kill lice that hatch from eggs the first dose didn’t reach.
- Clean or replace bedding, collars and grooming tools, and treat all dogs in the household.
- Clip and gently clean badly matted areas as your vet advises.
Prevention
Keeping your dog on regular, vet-recommended parasite prevention, maintaining good grooming and hygiene, and not sharing tools between dogs all lower the risk. Most dogs on routine flea/tick prevention rarely get lice.
