These tiny, flat, and wingless insects can cause itching and irritation as they make themselves at home in human hair. But what about our canine friends? Can they catch lice from us? The short answer is no, dogs can’t get lice from humans!
Lice are species-specific meaning human lice stay on humans, however, dogs can become infested with dog lice. Keep reading to learn more about canine lice, how to get rid of them, and why you luckily won’t find these particular parasites in your own scalp!
What Are Canine Lice?
Humans have their own species of lice, the most common being Pediculus humanus capitis (head louse). Dogs can be infested by three species of lice:
Trichodectes canis, a chewing louse found globally which primarily infests dogs and closely related wild canids, including coyotes and wolves.
Linognathus setosus, a bloodsucking louse.
Heterodoxus spiniger, a biting louse which is rare in North America. It tends to affect wild canids and is mainly in dry tropical countries, such as Egypt.
Human lice cannot live on canines and vice-versa. So, now you can have the peace of mind knowing that your pup won’t catch lice from snuggling up with you on the couch!

How Often Do Dogs Get Lice?
Now that you know that dogs can’t get lice from humans, you might be wondering how often dogs actually do get lice. The truth is, while it’s not that common, it’s not unheard of either. Dogs can get lice from other dogs, particularly if they spend time in close quarters with an infested pup.

In general, lice infestations are less common in dogs compared to other parasites like fleas or ticks. However, it can still happen, especially in environments where dogs are in close contact with each other, such as kennels or shelters. Additionally, dogs with compromised immune systems or poor grooming habits may be more susceptible to lice infestations.

Excessive scratching or biting at the skin
Visible nits (lice eggs) or adult lice in the dog’s fur
Redness or irritation of the skin
Hair loss or thinning in affected areas
If you notice any of these signs in your dog, consult with your veterinarian for proper diagnosis and treatment.

Other Tips for Keeping Your Dog Free of Lice
Avoid any contact with other infested dogs. If you know or suspect that another dog is infested with lice, avoid letting your dog come into close contact with them. Lice are primarily spread through direct contact, so minimizing exposure to infested canines can help reduce the risk of transmission.
Clean their living environment. Lice can survive in your dog’s environment, so keep it clean and well-maintained. Regularly clean your dog’s bedding, toys, grooming equipment and living areas to remove any potential lice or eggs. Vacuuming carpets and furniture can also help get rid of lice and their eggs.
Talk to your vet about preventive strategies. These may include medicated shampoos, spot-on treatments, or oral medications that are safe and effective for preventing lice infestations. Your veterinarian can recommend the best option for your dog based on their age, health status, risk and lifestyle.
Keep an eye out for any signs of lice infestation in your pup. These can include excessive scratching, visible nits or adult lice in their fur, redness or irritation of the skin, or hair loss. If you suspect that your dog may have lice, consult with your veterinarian for proper diagnosis and treatment.
