There has been much discussion in our agility and obedience community recently concerning the fact that the tick/flea population evolves and can become immune or resistant to one type of chemical, and if that happens you might notice that what you use is no longer working.  Several people I've discussed this with have told me that their vet recommends switching brands from time to time.  Almost everyone uses Frontline Plus, but many are switching to K9 Advantix. 

I purchased some K9 Advantix but haven't used it yet... I've always used Frontline Plus, and it has worked well for me, but because I've used it pretty much exclusively for many years... I too decided to switch.

Does anyone here use K9 Advantix?  If so... has it worked well for your dogs?  It's supposed to repel and kill fleas, ticks AND mosquitos.

I know this is an age-old subject, but because I've never used anything but Frontline Plus, I'm just curious as to what experiences others have had.

Thanks!

I rarely need to use any type of flea product on Dar & Lucy, but when, or if, I start noticing fleas (and I check them daily in the summer months) I usually just use Bio-Spot.

I thought there was a recall on this brand some time ago. Something with regards to the active ingredient it contains. May want to check it out before using the product again.

Nora, just an FYI. Advantix uses the same drug as Advantage, plus another medication(same company) . I believe it is Imacloprid? something like that...lol Anywho, this is what I believe Jack was sensitive to and had the tremors because of. Not saying that any other dog would, but I do feel that it is worth mentioning. These are little dogs with higher sensitivities than bigger ones, so it is something to keep an eye out for. I still haven't tried Frontline, but I think I will soon as it has been very warm and I know the fleas will be showing up soon!!! Still a little nervous though. Good luck with whatever you choose!
