Credelio is known to kill adult fleas quickly and effectively. For comprehensive flea control, you should treat all the animals in the household. Also, your dog is continuously exposed to fleas from the environment. New fleas may continue to jump on your pet and infest them. Credelio kills these fleas shortly after they are attached to the dog.

When you miss a dose, give one dose immediately with food and continue with the monthly dosing schedule.
