K9 Advantix Flea Control for Dogs Over 55 Pounds (6 Applications)

We have been using this product for a year now, and we haven't found one flea on our dog yet! I highly recommend this product to other dog owners.

My dog spends lots of time outdoors and with other dogs, and she's flea/tick/mosquito free. Wish they made it for people!

After trying several other treatments and collars, the fleas would not go away. Our dog's fleas were gone in a couple of days. No more scratching and we haven't seen any fleas jumoing around.

This works much better than Frontline or Frontline Plus, when there is a serious flea and or tick outbreak in the area we remain unaffected. While using Frontline PLus we did have good control on fleas but the ticks were immune to it. Ticks lose the fight with Advantix, it kills them so fast that even if I do see one on the dogs it is already dead! Using for two years now...

After various flea-killers failed to do their job on my Big Girl, I thought maybe they were counterfeit so, trusting Amazon, I bought this. After applying 2 weeks ago I'm still brushing out live fleas. maybe they've developed an immunity--this stuff used to work but now does about 75%. Anybody out there got a sure thing that kills the fleas but not the dog? (nothing Chinese, please!!)
