What is the common name for Ctenocephalides canis?

The dog flea.

The common name for Ctenocephalides canis is the “dog flea.” This parasitic insect is a member of the flea family and is primarily associated with dogs, although it can occasionally infest other animals, such as cats, foxes, and even humans under certain circumstances. Dog fleas are small, wingless insects that are dark brown in color and possess a laterally compressed body, which helps them move through the fur of their host. Like other fleas, they are equipped with powerful hind legs that allow them to jump long distances relative to their size.

Dog fleas are ectoparasites, meaning they live on the external surface of their host, where they feed on the host’s blood. The bite of a dog flea can cause irritation, redness, and itching, which may lead to excessive scratching and skin damage in the host. In severe infestations, these fleas can cause anemia, especially in young or weak animals. They are also vectors for various diseases and parasites, such as the transmission of tapeworms (Dipylidium caninum) when ingested by the host during grooming.

While Ctenocephalides canis primarily targets dogs, it is often confused with Ctenocephalides felis, the cat flea, which is actually more common and can infest dogs as well. Effective flea control involves treating the animal, its environment, and sometimes other pets in the household. Flea preventatives, proper hygiene, and environmental management are key to preventing and controlling infestations of dog fleas.
