Fleas can cause your pet to develop severe itch, allergies, and skin infections. Fleas also carry blood parasites that are transmitted to cats and dogs when they feed. The tapeworm has part of its life cycle in the common flea and is one of the many parasites that your pet can contract from the flea.
It is common belief that fleas only need to be treated in the summer months, however, the flea life cycle persists all through the seasons and if animals are not treated all year round, large infestations can result. An effective flea prevention program will also consist of cleaning the pet's living environment.
