The most common external parasite found on pets, fleas can be a major problem for dogs, cats and the whole family. Simple itching caused by fleas can be irritating enough for a dog or cat. But fleas can cause more serious health problems too. Fleas are also responsible for transmitting the dog tapeworm (Dipylidium caninum) to dogs, cats and even humans. In addition, fleas can spread bacterial diseases, too.
Some pets develop severe allergies to flea bites (called flea allergy dermatitis) and develop signs, such as itching, that may last long after the fleas have gone.
While outdoor pets are more susceptible, your dog or cat may be exposed to these blood-sucking parasites anywhere: in your own backyard, on walks or even in your own home. When it comes to fleas, the faster you get rid of them, the better!
A flea can jump more than 100 times its length (vertically up to 7 inches and horizontally 13 inches). That's equivalent to an adult human jumping 250 feet vertically and 450 feet horizontally.
Rarely do fleas jump from dog to dog. Most flea infestations come from newly developed fleas from the pet's environment.
