Fleas
Fleas are biting insects frequently encountered in dogs and cats. The most common flea is Ctenocephalides felis, a cat flea but which is often found in dogs. The adults stay on the animal and feed on blood by bite. The females lay eggs (up to 50 per day) which fall into the animal's environment, give several larval stages, then a nymph in its cocoon, finally a “pre-emergent” adult which remains under the shelter of the cocoon several weeks, sometimes up to 6 months. During the passage of a new host, the pre-emerging stages emerge from the cocoon, pass over the host and sting it. Contamination mainly takes place in the animal's environment when it finds itself on "hot spots" (sleeping areas, rugs, carpets, armchairs, wooden floors, car, etc.) ...
