Dog fleas (Ctenocephalides canis) are common pests in Europe, Africa and Asia, and are lesser known in North America. They are extremely similar in appearance and behavior to cat fleas, and the two are often times confused. The differences between them are best distinguished through microscopic study. In North America, fleas known as cat fleas affect both cats and dogs.
Fleas extract and consume the blood of host animals in order to survive. Neither cat nor dog fleas leave the host voluntarily and will typically remain with one host throughout their lifespan. However, if dog fleas are forcibly removed from their host, they will locate a new host or return to the original host if possible.
As with any flea species, hosts and surrounding areas need to be treated in order to effectively eradicate a dog flea population. A veterinarian can discuss safe and effective treatment methods for your pet, but contact your local pest control expert to discuss science-based solutions and extermination options for your home.
