Please let me know as soon as possible which of the Flea Drops work best & why. We just moved into a new home, has been treated for fleas inside & out, but I use Advantage to help keep the fleas off my dogs (3), and your website shows Frontline - of which I have never used - please respond and explain the difference & if you carry Advantage products as well.
Advantage is the best for fleas. Frontline is the best for fleas and ticks. vetcare
