While other flea treatments may simply kill fleas on contact, Comfortis actively repels fleas for a full 30 days. Since there is no mess on their fur, there is no time period where they need to be kept away from children or other pets either. Safe for use on cats and dogs 14 weeks and up, start making flea medication a pleasant experience today, with Comfortis chewable tablets.

Rated 5 out of 5 by Furlee comfortis is the best flea preventive medicine out there!
if you have given your dog the popular flea medicines such as advantage and they still have fleas you must try comfort if. We used to have trouble every summer with fleas on our dogs and tried all of the liquid applications out there because they were slightly lower cost. With comfortis we have had zero fleas over the past two years on our dogs and if you shop around the price per dose is not that much more than the liquid applications so it is definitely worth switching.

Rated 5 out of 5 by BuddyBoo Best flea killer on the market!
After trying numerous other flea prevention products with no success for several months, we finally heard about and tried comfortis and our dog was feeling better within the day. Totally effective.

Rated 2 out of 5 by Gingerbean It works! It doesn't work!
This was a life saver last year for my very sensitive Golden Retriever. She is highly allergic to fleas and Frontline and Advantage were ineffective against these pesty varmints, Out of frustration and sympathy for my poor furry best friend, I had no choice but to fork up the cash and take the risk of trying something new. Comfortis worked miracles. The varmints were gone and my best friend was finally healing from her constant scratching and biting. She had a 4 month break without the medicine and still no sign of fleas. The 5th month I put her back on Comfortis and by the 6th month she was covered in fleas again. After treating my entire house and best friend and two consecutive months of administering Comfortis, the fleas are still with us and worse than ever before. My Golden now has hot spots, which she's never had in her 7 years of life, and an ear infection. She's miserable which makes me miserable. I'm so confused with this product. For the price, I should not have the issues I am having. Could it be that the fleas are now resistant to the active ingredient in Comfortis?

Rated 5 out of 5 by bungaloebill224 great product
Make sure you thank the pharmicutical company for making a pill form for cats that releave fleas. Next suggestion for them, pill form that not only kills fleas, but also de-worms cats. How about pill form for their annual shots like for rabies and feline lukemaia?

Rated 5 out of 5 by SammySam Finally!
Finally something that has worked! Our golden retriever has been given flea bath after flea bath, and also that oil that is put on his back again and again. We have flea bombed the house over and over, and he constantly has them! Well finally I asked the vet what he'd suggest and he suggested this! Now, it's only been a few days since he's eaten it, but it worked!

by EClay222 Effective but Expensive- I would still recommend it highly
Very effective for our 3 Dalmatians.
Pros - Effective
Cons 1. - not in a chewable tablet. Not yummy by our dogs, so a little harder to give.
2 Expensive - wait for discounts
I would recommend trying it it. We have used Comfortis for 2 years and not a single flea.
