Flea pills for dogs typically work by releasing an insecticide into the dog's bloodstream. When fleas bite the dog, they ingest the insecticide and are killed. Some flea pills work by interrupting the flea's life cycle, preventing the development of flea eggs and larvae. This helps to control flea populations and prevent re-infestations. It is important to follow the instructions provided by the manufacturer when administering flea pills to ensure their effectiveness and to avoid potential side effects. If you have any concerns or questions about flea pills or flea control for your dog, consult with your veterinarian.

Some flea pills may require more frequent dosing, while others may have longer-lasting effects.
