Rated 5 out of 5 by Love this product I've been using Comfortis for several months now and have had no issues with fleas whatsoever. My dog takes it just fine, no side effects that I've noticed. I would recommend this product. November 23, 2014
Rated 5 out of 5 by One of my dogs eats fast, the other I have to hide the taste in something strong like sardines. Other products killed flees. Only Comfortis stopped Ticks for more than a month. November 22, 2014
Rated 5 out of 5 by 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 Great product. Is the product that my vet suggested and he is great and has always steered me right. October 31, 2014
Rated 5 out of 5 by 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. October 30, 2014
Rated 2 out of 5 by 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? October 20, 2014
Rated 5 out of 5 by 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? October 20, 2014
Rated 5 out of 5 by 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! October 18, 2014
