The Proper Way to Put Flea Medication on a Dog
For every pet owner, preventing fleas is a major part of keeping a pet happy and healthy. Flea medications such as Frontline, K9 Advantix and Advantage are easy to apply, safe, waterproof and effective. The medications can last up to three months after application. They kill adult fleas between one and 12 hours and larvae within 20 minutes after application. They are designed to control flea development by killing fleas before they lay eggs, therefore breaking the flea life cycle.
Open an applicator. This may require scissors or a knife.
Part the dog's fur at the base of its neck between the shoulder blades.
Place the applicator to the skin and squeeze out the contents.
For dogs up to 20 lbs., apply medication to a single spot on the skin on the back between the shoulder blades. For dogs 21 lbs. or more, apply medication to three or four spots along the skin on the back from the shoulders to the base of the tail.
Throw the applicator in the trash.
