Rated 4.5 out of 5 by 125 reviewers.
Rated 5 out of 5 by Great Product I love Trifexis for my dog. It kills fleas and it's eggs very quickly. It also protects him from heartworms, hook worms; etc. All in one chewable tablet once a month. Super convenient. I highly recommend Trifexis for its efficient effectiveness, ease of use and convenience. Additionally, the discounted price at Pet care RX is fantastic. Thank you guys for a great product at a great price. May 2, 2016
Rated 5 out of 5 by Vet Recommended Vet recommended - best price found through your service. The old product seemed to become ineffective so this was recommended by Vet. Seems to be working fine. May 1, 2016
Rated 4 out of 5 by tad expensive One pill seems to do the trick. Just a bit pricey, even from PetCareRx. March 27, 2016
Rated 5 out of 5 by No complaints.... This product was recommended by my veterinarian, and has worked effectively for a long time. March 21, 2016
Rated 5 out of 5 by This is the best product for fleas that I have found for our dogs. No other product has been as effective for our dogs to keep fleas off. It also has the added bonus of protecting them from heart worm too so it is a great value! March 7, 2016
Rated 5 out of 5 by Trifexis has been great for our Doberman!!! Our vet recommended Trifexis for our young female Doberman and she has been on it for over 3 years now. It works great for us and is very easy to use - just one pill, once a month - PetCareRX is very easy and economical to use, they even keep track of when you need to re-supply!! Outstanding Service!!!

Rated 5 out of 5 by This product is amazing We have used this for years and our dogs have NEVER had any fleas or heartworms. We live in middle TN in the woods, so we have TONS of fleas and ticks. It is well worth the money. February 8, 2016
Rated 5 out of 5 by Lives up to the good reviews Our dog won't chew it, but she loves the treat she gets afterward! Sometimes it makes her lethargic for a day, but we have never seen a flea. January 21, 2016
