As a former Veterinary Technician I have considerable experience and knowledge about fleas and their life cycle. However, you don't have to be a technician to do a google or wikipedia search to learn a little bit before writing an ignorant review. The vast majority of the bad reviews I have read here, are obviously (to me) from people who really do not understand where fleas come from and what you have to do to eliminate them.
Here's the thing: 90% of the flea population that feeds off of your pet are NOT ON THE ANIMAL RIGHT NOW. That's right, the vast majority of the pests are actually on your floors, carpets, furniture, pet beds and so forth waiting to hop on Spike and Fluffy when they are hungry. Fleas feed, then jump off the animal, while some more of their family jump on and start feeding in their place. To truly manage the flea problem requires TREATING THE ANIMAL AND THE PREMISES. If you do not treat the premises (including the yard) you will never get ahead of the problem. Sevin dust in the yard or some pyrethrin-based spray have been effective for me for many many years.
Also, the lack of effectiveness that people think they are seeing is not because the product is not as good, it is because the fleas have become tougher over the years. You just have to attack the problem on all fronts and be as persistent as the pests themselves. Treat the animals and the premises and don't let up.
Now, I am going to save some people a lot of money. The drug in Advantage for Dogs and Advantage for Cats is exactly the same drug (Imidacloprid) at the same concentration.
If you buy this "Large Dog" package, you get four 4ml tubes. If you then empty those into a vial or vials, you can use a syringe (without needle) to apply the right dosage to your dogs AND cats. In fact, if your cats are under 10 pounds, you can get 10 cat doses out of each of these vials. That's a real bargain!
Advantage II is the same, but adds Pyriproxyfen for the full life cycle coverage.
Use the following chart and you will be fine.
Cats up to 9 pounds 0.4ml
Cats 10+ pounds 0.8ml
Dogs 11-20 pounds 1.0ml
Dogs 21-55 pounds 2.5ml
Dogs 55+ pounds 4.0ml

We have three dogs & two cats & occasionally a few hundred if not thousand fleas. We use different doses to cover the whole herd.
We used Advantage when we lived in TX & it worked great. Then we moved to MO, got a new vet who sold Frontline in bulk & gave one free when you bought four. He would just fill syringes with a prescribed amout & put those in a medicine bottle. We thought, sure, whats the difference & went on as usual.
The frontline is a good product & we couldnt really tell any difference so we just didnt think anymore about it.
But after a few months one of our dogs started to have allergic reactions to fleas.
For reasons I wont go into here, we switched Vets. Our new Vet didnt sell Frontline in bulk so we purchased the Advantage from her that came directly from the maker, Bayer.
Wow, what a difference! I put in on the whole crew at 8 am & by noon the scratching & biting was almost non existent. I did a search for fleas & the ones I did find were either dead or moving so slowly they were easy to catch & kill. Two days later we have no fleas.
Now I should add two things here.
First, I also treated my lawn with a 10 lb bag of flea, tick & ant killer which Im sure helped. At least as far as re-infestation is concerned.
Second, I suspect that the bulk Frontline that I was purchasing may have been weakened by age or the way it was stored by the Vet & transferred to me in syringes. So I would suggest that anyone thinking about purchasing in this way, think again.
Lastly, my wife & I are considering using Advantage & Frontline both. Possibly switching them every other month in hopes of keeping the little buggers from developing resistance. I dont know if that will help but it couldnt hurt.
Best Deals for Bayer Topical Flea Treatment for Dogs
In the "old days" before Advantage and Frontline became available it was the tiresome routine of wash the dogs, spray the house and lawn with noxious chemicals and repeat. It often took an entire Saturday. These drops were a blessing. Now the Advantage seems to be losing it's effectiveness. My vet agrees, saying they need to tweek their formula. I've started using Frontline one month, then Advantage the next month. It's the only way to keep fleas away.
Honest reviews on Bayer Topical Flea Treatment for Dogs
Our outdoor area is suffering through a major flea infestation. Having tried frontline without success, we waited some time before trying Advantage. Worked like a charm.

I bought Advantage for both cats under 9 lbs and dogs under 10 lbs for my parents. They have 3 cats and 2 dogs that became subject to a plague of fleas during the 2 weeks I was visiting.
I've used Frontline for my 2 dogs in the past and was very happy with it, but for 5 animals Frontline is a big expense. Advantage is a little less expensive. I researched the differences between the two and basically it comes down to Frontline will also handle ticks whereas Advantage is just for fleas. People seemed happy with both products.
Biospot is cheaper than both but totally useless. I was a little anxious about using Advantage without knowing if it worked as well as Frontline.
We put it on all the animals the afternoon the package arrived. That night one of the cats was sitting on me. I got up to go to the store and noticed two fleas on me. Later she was on me again and when I got up there were 8! She moved to my father's lap and when he got up he had 17 on him. All the fleas were dying and moving from their food source, but alas it was too late for them.
I didn't realize how many fleas the animals had. Advantage worked great. I am not sure how it will do in the long run, but the pets are relieved for now.
I still use Frontline for my dogs because we go hiking where there are ticks galore. Advantage is a good solution for my folks because their pets stay indoors or their yard. I think the applicator is easier to use with Advantage. None of our pets had any adverse effects from using either product.
