Using Frontline and Advantage Together

**Burns** · 05-07-2008, 06:26 PM

Up to this point, I've been using Advantage Multi for heartworm, flea and intestinal parasite prevention. But since we go on lots of walks in the woods, I want to cover Red for ticks as well, which Advantage Multi doesn't do. So I have added Frontline Plus.

My Merial rep said not to use Advantage Multi and Frontline together but to use Heartgard and Frontline instead (I have a feeling my Merial rep only wants me to use Merial products...), but my Bayer rep said it was fine and the two products are safe to use together.

I have done reasearch on VIN and spoke to a doctor I work with and the consensus has been that a lot of people use Advantage and Frontline together since there is a increasing issue of fleas becoming resistant to Frontline. My first inclination was to just do the Frontline and Heartgard and see if the fleas became and issue, but honestly, I don't want to wait until I see a problem to fix it. I'd rather prevent it altogether. From what I've read and heard about using Advantage and Frontline, is to stagger their applications by a couple of weeks.

My question is - do any of you use Advantage (or Advantage Multi) in conjunction with Frontline? Have you had any problems doing this?

I use Frontline and Heartguard. I don't think I would be comfortable mixing two flea medicines. I'm already parinoid about putting chemicals on them that they absorb in their blood but I know I must to prevent fleas and most important, ticks. I picked one off of my older dogs eyelid yesterday but it is a few days past time to dose them. I'm waiting for my husband to help me hold them still. The Doberman is the only one who is good when I do things to him, the others have to be held down.
