Advantage Multi is a monthly, bathing resistant, topical spot on,
heartworm preventative for dogs and cats. Advantage Multi is made by Bayer,
who also make K9 Advantix and the original Advantage Flea Control.
Bayer introduced the now very popular advantage flea control products for dogs and cats over ten years ago.
The traditional advantage flea control, still available today, is an easy to apply, monthly, topical spot on just for fleas
that does not control heartworms.
But Now Bayer has taken the traditional advantage flea control one step
further and added heartworm protection
to its newer product, Advantage Multi
. The initial "fleas only" Advantage product introduced
ten years ago, does not require a
prescription from your veterinarian, however, new Advantage Multi does. This is because
it is important to make sure your pet is free
of heartworms before you begin any heartworm protection regimen. Heartworm meds can do more harm than good
if your pet is already suffering from heartworm disease. Consequently, heartworm medications like advantage multi require
a prescription to show that your pet is currently heartworm free. Heartworm medication prescriptions
usually last one year.
