Synopsis
CAPC Recommends All dogs should be treated year-round and throughout their life with flea control products to limit infestations on the pet and prevent establishment of flea populations in the home Recognize that flea infestations, once established, may take several months to bring under control and that to achieve control, every pet in the home must be treated Address flea infestations on pets as a public health concern; people in
Species
Canine Ctenocephalides felis (cat flea) Ctenocephalides canis (dog flea) Echidnophaga gallinacea (poultry sticktight flea) Pulex simulans Pulex irritans (human flea) Xenopsylla cheopis (oriental rat flea) *Other flea species may on occasion parasitize dogs Ctenocephalides felis female Ctenocephalides felis male Echidnophaga gallinacea female Echidnophaga gallinacea male Pulex simulans female Pulex simulans male Xenopsylla cheopis female Xenopsylla cheopis male
Disease
Annoyance and pruritus are common complaints. Heavy infestations may lead to iron deficiency anemia and death, particularly in young animals (dogs, cats, goats, cattle, and sheep).
Prevalence
Ctenocephalides felis is the most common ectoparasite of dogs in North America. Ctenocephalides felis is uncommon where relative humidity remains below 50% (desert southwest and Rocky Mountain states).
Diagnosis
Physical examination of the host is the first step in identifying fleas or flea feces within the hair coat. Flea feces can be removed with a flea comb and placed on a wet towel; the feces will dissolve and turn red.
Treatment
Comprehensive flea-control programs should eliminate fleas on pets, eliminate existing environmental infestations, and prevent subsequent re-infestation. Moderate to severe infestations may take several months to bring under control.
Control and Prevention
Administer preventive flea and/or tick products as soon after birth as possible (consistent with label claims) for the life of the pet. However, because substantial geographic differences occur in flea prevalence and seasonality, prevention programs should be tailored to needs of the individual pet.
Public Health Considerations
The common flea of dogs, C. felis , transmits a number of zoonotic agents, including those that cause cat scratch disease ( B. henselae ), murine typhus ( R. typhi ), flea-borne typhus ( R. felis ), and tapeworms ( D. caninum ).Ingestion of infected fleas by children has resulted in development of adult D. caninum (tapeworm) in a large number of pediatric cases.
