It matters where you put flea treatment on a dog. Spot on flea treatment should only be applied to the back of a dog's neck, at the base of their skull, directly onto the skin. Do this unless otherwise instructed. This hard to reach spot makes it best place to apply flea treatment so it can't be licked off by a dog.

Apply flea treatment for dogs on the back of the neck, squeezing on all of the liquid dose directly onto the skin. This makes sure the flea treatment solution is absorbed by the dog's skin oils to be effective to get rid of fleas. Applying dog flea treatment on the skin, not on fur enables the flea treatment to work faster to kill fleas.

Afterwards, make sure to let flea treatment on a dog dry for 48 hours so it is 100% effective. No rain. No baths. No licking.
