Oral Flea Medication for Dogs

Pills to Kill Fleas on Dogs

Adult fleas are permanent parasites of their host. They rely on blood meals to survive and reproduce. As a result, they will remain on the host unless they die or are dislodged through grooming.

Oral flea medications typically contain the active ingredient nitenpyram, an insect neurotoxin. Adult fleas will begin to die 30 minutes after a dog consumes a pill. 90% of the corporeal flea population on the dog will die within 4 hours.
