  • It's working on my beasts
I like that it doesn't smell terrible. And not even bad for very long. It's nice and oily so I know it's coating their fur well. Price is economical. One box did all mine for more than a month

  • Really works!
I have tried many different versions of flea medications, both prescribed and available over-the-counter and this is the best one I have ever come across. In Florida we have some really vicious fleas that seem to be immune to some of the other products that are on the market. This is the only over-the-counter product that works for my pets and stops the flea cycle. The first time I ever used Advantage II, was on my cats. I applied it on the back of their necks and left them sleeping on my bed. When I came back, I couldn't believe my eyes. There were dead and dying fleas all over my bed and it was completely disgusting. There were also these small light orange things that may have been flea eggs and small white worms. I have never seen that type of thing happen with any other flea product before and I've tried most of them. I now apply the product and then lay down old towels and put the pets in a room by themselves. After a few hours I come in, throw the towels away and clean the room completely from top to bottom and vacuum thoroughly. We have not had a flea infestation thanks to this stuff. I purchase the extra large dose for my 4 dogs and give each of my pets the amount recommended by my Vet from the one vial. One extra large dose is enough flea medication for all four of my dogs. I highly recommend giving Advantage II a try. It really does work to kill all the life stages of fleas and will break the flea cycle. ... show more

  • Fleas r Gone
Works great on cats too with no bad side effects.

  • Almost great
This works very well on fleas but, not so great on ticks. I don't know if they've changed the formula or, if there's just a bad outbreak of ticks this year. My animals are outdoor animals and I have had to pull ticks off them every day, even though they are properly dosed with this medication.

  • Thank you
Thank you from our dogs. This is the only flea medicine that will work for them. Thank you, too, from our CATS! Now they aren't covered with the dogs fleas! Everyone is happy...except the fleas.

  • Only worked for 3 weeks, Not as effective as it was?
We used this off and on on our other dogs for years and a dose seemed to last for months. On our new dog, slightly smaller even, this says it's the exact same product but effectiveness only last about 3 weeks. Bought a second batch, different supplier as we thought maybe we got a bad batch - exact same results. Will be switching to another product when next in need. ... show more

Ok, so we have been buying advantage for years for our dogs but this stuff really takes flea prevention to a whole other level. THIS STUFF WORKS!!!!!!!! And immediately too. After we put this on our Basset Hound (who is a low rider and gets the worst fleas), there was a pile of fleas where he was laying. The fleas literally start to die and try to get away within mere literal seconds. Just as soon as you put the Advantage II on the dog, it is immediate. And it works for a month. This stuff is crazy. Like we said, we have been buying flea medicine for our dogs for years and years and years and just recently have we decided to give Advantage II a chance and we are so glad we did and we will never look back at other flea prevention medicines. We live in Florida and have a major flea problem and this stuff literally changes our lives. Thank you for an awesome product. Anyone who buys anything else is just not treating their animals right because this stuff is the only flea prevention that needs to be used fro your pets peace of mind and your own peace of mind. ... show more
