July 2010: Capstar for Dogs is highly recommended by vets and dog owners for rapidly and safely killing fleas. Within four hours after this oral pill is administered, it kills 90 percent of fleas on your dog. This is faster than topical flea treatments and safer because there's no risk of exposure to chemicals during and after application. However, Capstar doesn't kill flea eggs or larvae, which can lead to re-infestation, and its effects don't last as long as topical treatments. Veterinarians who recommend Capstar say it has fewer side effects than other flea control products. No prescription is needed to purchase Capstar, which can be administered daily until fleas disappear. However, Capstar for Dogs is only suitable for dogs 25 pounds and larger. For small dogs and puppies, use Capstar for Dogs and Cats instead. It is identical to Capstar for Dogs, but in a smaller dosage. More information is available here.
If you also want to prevent flea eggs and larvae from developing, vets recommend using Program Flavor Tabs for Dogs (*Est. $60 for a six-month supply) in conjunction with Capstar. Topical treatments, such as Advantage II for Dogs (*Est. $60 for a 6-month supply), are effective at killing fleas and also kill eggs and larvae.
