Simple facts about dog fleas:
Fleas are probably the most successful creatures on the planet in terms of reproduction. There are over 2,400 species and they are difficult to control for a variety of reasons: One female flea will produce 25,000 offspring in one month. An unfed adult can live for several months. The chemicals used to eradicate adult dog fleas have no effect on the eggs. Fleas are very good at mutating to resist new pesticides.
Fleas are a menace to dogs! They cause allergic dermatitis, tapeworms, and anemia. Most of the eggs are not laid on the dog but in the dog’s bedding, in the rug, and on the furniture. It is extremely difficult to eradicate fleas completely. The most you can hope for is to control them and to keep your dog reasonably comfortable during the warm, moist flea season.
The best way to control dog fleas is to remove them from your dog and your house. Take him to a groomer for the day and have him bathed with veterinarian-approved flea shampoo. Spraying or dipping him with a residual pesticide has little or no lasting effect. While he is out of the house, hire a company that uses a non-toxic product to spray the carpets...
