Dog Lice vs Fleas: Appearance
One of the main differences between dog lice and fleas comes in the form of their physical appearances. Dog lice are light in color, often a yellow or white, while fleas are notorious for being dark brown or black bugs. While you likely can’t tell their main physical differences using the human eye, fleas have a rounded lower half, while lice have a more elongated and uniformly shaped body.
You will recognize a dog lice vs a flea based on the coloring alone.

Let’s talk more about these pest’s behavior, as this will further help you identify them.
Dog Lice vs Fleas: Behavior and Mobility

Another difference when it comes to dog lice vs fleas is found in their behavior and mobility. Fleas are well known for their ability to jump and leap great distances; this is not a feature that lice share. Lice are much slower and less capable of jumping when compared to fleas. While this may not seem like a distinct difference, it greatly affects the lifestyles of these two pests.
For example, lice attach to animals via the hair shaft, clinging and living on the hair for the remainder of their life. Fleas are much more mobile, using their jumping ability to move from animal to animal, infested area to infested area. Fleas have a much better chance of surviving than lice do, given their mobility. However, lice are less likely to be noticed right away when compared to the coloring of fleas.
Dog Lice vs Fleas: Diet
Another key difference between dog lice and fleas is their choice of diet and nutrition. Dog lice prefer to eat dead skin cells and skin secretions, while fleas feed off of an animal’s blood exclusively. While both pests leave you and your pets feeling itchy, this is a clear and present distinction to be made between these two bugs.

Dog Lice vs Fleas: Reproductive Habits
The reproductive habits of dog lice and fleas are very different as well. Dog lice lay their eggs once they have landed on an unsuspecting animal, while fleas prefer to lay their eggs in undisturbed areas, such as carpeting. Fleas also require blood in order to lay their eggs, while lice do not.
Lice attach their eggs to an animal’s hair shaft until they hatch, usually within one to two weeks; flea eggs hatch in a similar timeline, though they can hatch in as little as a few days if conditions are right. Fleas differ from lice in that they don’t land on an unsuspecting animal until they are fully grown adults, while dog lice remain attached to your family pet for the entirety of their life cycle.
FAQs (Frequently Asked Questions)
Does flea treatment kill lice on dogs?
Depending on the flea treatment, yes, most commercial flea treatments treat lice on dogs as well. However, you may need to schedule a grooming appointment for your dog to specifically treat lice if you think that your dog has been infected.
Do dog lice and fleas bite humans?
Dog lice prefer to bite only dogs, while fleas will bite both dogs and people. However, even fleas prefer to bite dogs rather than humans, given their ability to hide in a dog’s fur without being noticed. Humans can get bitten by a specific type of lice or louse, but are not likely to be bitten by dog lice.
