When Can You Use Flea Medicine on a Puppy?

Most modern flea medications are safe to give to puppies when they are about eight weeks old, as a general rule.

Each flea medication uses different chemicals and pesticides as active ingredients, so it is imperative that you reference the packaging for the specific flea medication that you are targeting for more information.

Flea medications are required to include this information on the insert included in the packaging, and many medications print the information directly on the box itself.

If you are having difficulty locating it or need more information, we recommend you contact your local veterinarian.
