      Don't Waste Your Money!

      Comments about Bayer K9 Advantix 10 (10-lbs and under):

      I just bought this product after reading some good reviews about it. The company sure does a good job at saying it repels and kills. Well it doesn't! After having applied it 6 days before, i found a tick on him that was biting already. I thought it was supposed to repel and kill fleas and ticks? My dog had 1 bath, 5 days after application and had not gotten wet at all in between. I live in a city and he hadn't been anywhere near tall grass. I need this product to work while hiking etc. I am moving to an area with deer ticks soon, and will definitely not trust this product to protect my dog.

          Kills fleas? None of these fleas.

          Comments about Bayer K9 Advantix 10 (10-lbs and under):

          I had been giving this product to my dogs monthly. I took them to boarding, and they came back with fleas. On the box, it says that Advantix II kills fleas starting at 12 hours from administering the medication; it's been three days now, and they have even more fleas. Thanks for nothing.

          Advantix No longer works

          By Dogwalker

          Comments about Bayer K9 Advantix 10 (10-lbs and under):

          I have used Advantix II for years and it worked great but not anymore. I don't know what they did to degrade but my dogs have ticks and fleas all the time and they never had them before using Advantix. I didn't mind paying the ridiculous price because it worked but now to pay that and it doesn't work, well, I'm looking for better now.

          Used to be reliable

          from Annandale, VA, USA

          Comments about Bayer K9 Advantix 10 (10-lbs and under):

          Have been using it for 10 years on our 65lb. brown Labradoodle. She loves to run in the bushes and woods and our yard has much wildlife running through even though we are in suburban area. I applied it as usual 7 days prior to finding an engorged tick on her. Not happy b/c it is expensive
