Dog flea

The dog flea (Ctenocephalides canis) is a species of flea that lives as an ectoparasite on a wide variety of mammals, particularly the domestic dog and cat. It closely resembles the cat flea (Ctenocephalides felis), which can live on a wider range of animals and is generally more prevalent worldwide. The dog flea is of veterinary importance because it can spread Dipylidium caninum. Although they feed on the blood of dogs and cats, they sometimes bite humans. They can live without food for several months, but females must have a blood meal before they can produce eggs. They can deliver about 4,000 eggs on the host's fur. The eggs go through four lifecycle stages: embryo, larva, pupa, and imago (adult). This whole life cycle from egg to adult takes from two to three weeks, although this depends on the temperature. It may take longer in cool conditions.
