Rated 4.3 out of 5 by 92 reviewers.
Rated 5 out of 5 Very efficient product I've used several different flea and heartworm products over the years and I find that Trifexis really does the job. It is not cheap and my dogs don't like it ( I have to shove it in their mouth which is no fun). October 23, 2014
Rated 5 out of 5 by Great price and service Unfortunately Banfield will not allow us to send our prescription from them to PetcareRX to get the better pricing on Trifexis :( We may have to find another vet. October 18, 2014
Rated 5 out of 5 by Pricey This is a pricey drug but effective my dog still itches but its not from fleas guess it's an allergy October 17, 2014
Rated 5 out of 5 by Great Flea Killer and Heart Guard I have been using this product for over 3 years for both of my dogs. Prior to this I was using just the flea killer but my veterinarian suggested I use the Trifexis, as it includes heart worm protection. It is a little bit more expensive but well worth for the health of my dogs . September 29, 2014
Rated 5 out of 5 by Trifexis works Our dog has been on Tifexis for 3 years now and we haven't noticed any problems. She doesn't like the taste so I do have to camouflage it with peanut butter. Since she has been on Trifexis we haven't noticed any fleas. So I guess the product is doing what it should be doing. September 16, 2014
Rated 5 out of 5 by Great item This product, so far, is the most effective method we have found to keep our pet flea-free, while protecting him from heartworm and other parasites at the same time. He tolerates the tablets well (although we have to hide the tablet in a larger chunk of food, such as a piece of cooked chicken, since he won't eat the tablet on its own) and has never had any negative side effects (such as vomiting or lethargy). We have been using this product for several years and our shih tzu will be 7 years old soon and is healthy and happy. September 12, 2014
Rated 5 out of 5 by Great product. Tastes and smells terrible! Very large pill! I have to grind it up and mix with peanut butter to get my dog to swallow it. Works great though. September 2, 2014
Rated 5 out of 5 by I like the product My dog does not like the taste, I have to put it down his throat but he is good about it. The only thing I don't like about it is it does not work on fleas so I still need the prevent tick collar August 18, 2014
