Top favorable review
very reliable product
I have been told at pet stores that Advantix works best, better than Frontline, so I always buy it. I once bought "extra large dog" size by mistake for a dog that is only 50lbs, but the manufacturer told me that I could measure each dose for my dog's size and thus save money. Ever since then I buy the XL size. It sometimes is a bit messy measuring and apportioning the dose but I feel it is worth it since these products are always so expensive!

Tick magnet
My dog was getting ticks so I purchased this. I have used it in the past with great success when it had the Bayer logo on it . The one I received has the Elanco brand logo on it. I used 1 bottle and It was like I used nothing at all. Mind you I walk my dog and when he comes in the house I would find 2 or 3 live ticks walking on him. So I figured ok maybe it didnt work or I didnt wait long enough. After about 10 days of this I applied another bottle and again nothing. He still kept coming in the house with ticks every time. So I'm not sure exactly what's going on but the package I received appeared to be authentic. All serial numbers matched and packages were sealed well. Never had this happen before but definitely going back to Frontline Plus.

It's the best!!
This is the only flea medicine I will use. It is the only flea medication on the market that repels fleas. All the other brands the fleas actually have to get on your dog and bite before it will kill them. Also this is the only medication that repels mosquitos as well. Just an overall great product!!

Finally flea free!
We struggled for a couple months with a brutal flea infestation. Three other treatment branda failed to do anything before we tried this product. Within 8 hours, my dog was finally flea free! It costs slightly more than those other brands, but for good reason. It actually works!

Mosquitoes too !!
K9 Advantix II is the only treatment that I will use on my German Shepards. And I say this for reasons in addition the killing and repellent... Most topical treatments are very oily, if your dog is an indoor pet staining is a big problem.. It is days until that oil finally dries, by this time everything your dog touched/l layed on/ slept on is oil stained. Just petting leaves your hands oily ! K9 Advantix dries within 24 hrs. This is a huge plus. Then comes the mosquito coverage..We hate when they bite us and then comes the possibility of the many diseases.. Same goes for your dog. diseases and with one bite heartworm !! No Way Man ! Not My Dogs ! With K9 Advantix II you get that extra piece of mind. I have been using it for several years and can thankfully say "No Issues at All "
