Looked at all the product descriptions.. But I'm not sure which one is the best choice. I have a niece and nephew under the age of five that come into contact with both my cat and my dog.. Stronger pesticides could be a problem, but my dog has a severe allergy to fleas. Currently using frontline plus it helps but not like I want it to. Basically I need input from other peoples experiences with the products.

Advantage...it's safest

What about Revolution? Or some other oral preventative? It really depends on your area which works best... ask your vet about the flea and tick population. For my area, Frontline works best, but for other areas any of the three you listed may work better.

I use comfortis, which is given orally not topically. I've had a lot of succes with it. The only thing disadvantage is it does not work against ticks.

Check a product called REVOLUTION, I think you will be happy with it. I have used it for 6 years and nothing else

I use promeris for my retriever and I give my pom some kind of flea pill. Both of them work great. Promeris is a strong flea killer, it is put on like frontline. The pill is self explanatory and it lasts for a month. Both of them have to be given from a vet, can't find them at pet stores

i use advantage on my dogs and cats and it works great!!

you can visually see dead fleas within an hour of using the product
