Similar to cat fleas, dog fleas have disproportionately small heads and six legs with the hind ones capable of jumping large distances.
Mature dog flea larvae are about 1/8-1/4” (2.5-5.2 mm) long. They are whitish, slender, eyeless and legless.

How to Get Rid of Dog Fleas in the House
Looking to get rid of fleas in the home? Homeowners should partner with a licensed pest control professional to develop a flea treatment program. Frequently vacuuming all upholstered furniture, floors and carpeting can help to remove flea populations and prevent them from laying eggs.
Pet owners should practice active flea management by keeping dogs on a leash when outside, bathing and grooming pets regularly, visiting a veterinarian annually, and using flea treatments according to direction.
Dog Flea Education
Habits
Dog fleas can live for about 100 days, during which time the females produce 400-500 offspring. Their biology and habits are the same as cat fleas. Dog flea eggs are deposited on dogs in between their hair. They usually hatch in 1-12 days. The larvae require feeding on dried adult fecal blood to complete development. Dog flea larvae spin cocoons and emerge after several weeks, usually when the temperature increases, or vibrations force them out. Adults seek a blood meal on the second day after emergence. Once a dog flea finds a host, it will feed, mate and lay eggs on it.
Depending on conditions, adult dog fleas usually only live for a few days, because normal dog grooming removes up to 50 percent or more of the fleas. Otherwise, they can survive for several months.
Threats
Dog fleas primarily feed on dogs but, when populations are large, they can be bite humans.
Fleas are the most common transmitter of the rare bubonic plague. They also transmit the bacterial disease murine typhus to humans through infected rats. Both dog and cat flea saliva can cause serious flea allergy dermatitis in pets and their debris has been reported to cause similar allergic reactions in humans. Fleas can also transfer tapeworms and cause anemia in pets, which is why active flea management is an important component of pet care.
