Rated 4.8 out of 5 by 198 reviewers.
Rated 5 out of 5 by It works wonders! Both our large dogs had been covered (think hundreds) in fleas for weeks no matter how many times we sprayed, bathed and dosed them with topical preventitives. Within 4 hours, the fleas were super active; by 16 hours, they were gone. We've only seen a handful since then and it's been a month. Hooray! July 27, 2014
Rated 5 out of 5 by Great Product w/o the wait-&-see worries. I can't speak highly enough of this product. I've had dogs I've just recently treated with this product for 16+ years and this has done the best and had quickest response. I've began using it 18 months ago as a result of my vet recommending it (since I didn't like different aspects of other products). This is my 3rd order and I will not go back to any of the other name-brand well known products I previously used. No more wasting money on any of the others I've used in the past. July 23, 2014
Rated 5 out of 5 by This is the BEST flea & tick medicine on the market!! I have livestock guardian dogs that live outside 100% of the time guarding our goat herd and this is by far isthe best flea & tick medicine I have ever used. One pill and the fleas are falling off within 30 minutes and within 24 hours, the dogs are not scratching or itching at all. Considering these dogs are not handled like the average dog, this has been the most convenient and effective flea & tick medicine I have ever found. I use it on my house dogs, cats and the LGD's. GREAT product!! Easy to use!! July 17, 2014
Rated 5 out of 5 by Works great and cheaper here than the vet I have read of some pets having side effects from Comfortis, but our four dogs have never had any issues. I hated squeezing those little tubes of topical flea treatment, and the smell and greasiness that I didn't want on my furniture. I also like that Comfortis takes care of all the fleas fast.

Rated 5 out of 5 by Super results One of our dogs is highly allergic to fleas and after trying many flea treatments, Comfortis was the only medication that eliminated the fleas and relieved his skin allergies. July 3, 2014
Rated 5 out of 5 by Works great We recently moved to the beach in California from Colorado and my dog had an allergic reaction to the sand fleas immediately. I tried the Advantage but had no luck, so I took her to the veterinarian and he gave me one dose to try. I was worried about side effects but there haven't been any. It wasn't easy to get her to take it but the effectiveness was great and it lasted almost 2 months! You have to get tricky as they can smell it in there favorite food and will refuse it, but I always manage to find a way to get her to digest it. I am so happy to find something that works, I had to write a review. Highly recommend this miracle pill :) June 27, 2014
Rated 5 out of 5 by Tip for dogs who don't want to take the Comfortis tablet The flea medication works great but my Golden Retriever hates taking it. (I guess it tastes bad to him). Now I cut the tablet into four pieces, freeze them then cover them in peanut butter. That seems to work. June 13, 2014
Rated 5 out of 5 by Excellent Flea Product I have used Advantix and Advantage for years with my senior dogs and they both worked well for some time. However, it recently in the past year stopped working and we had a terrible time with a major flea infestation. I tried switching to Frontline which worked a little better, but still, we had flea problems. So I reached out to our vet and he gave them Comfortis to use. It eradicated the flea issue immediately! I was amazed to find that just giving them their first dose, the fleas just disappeared from everywhere. I also like the fact that it is an oral tablet and not a topical. So no more worries about getting the topical on my skin or my children getting it on them from petting the dogs. I highly recommend this product! May 30, 2014
