    My big dog has been on Trifexis for several years and he has never had any side effects from it. It is a bit expensive from my vet and I am going to start ordering it online.
    The only negative thing I can say about this medication is, my dog hates the taste and won't chew it. My dog eats dry dog food but every month I have to give him wet dog food with the Trifexis tablet crushed up and mixed in it. This is the only way he will eat it.
    It would be nice if this medication would come in a capsule so I could just have my dog swallow it.

    Your Trifexis is expensive but I purchased from you because I was able to receive a Rebate on the cost by shopping on the Ebates website. Initially, I was given the $13.30 rebate but later was notified by Ebates that the rebate was cancelled, along with an earlier order rebate. I have emailed your customer service on several occasions but still do not have a response as to why my rebates were cancelled. As much as I like some of your products, I will not shop again unless the rebates are returned to me via Ebates.

      Comments about Trifexis for Dogs:

      I like that the product works for both fleas and heartworm. My only complaint is that the tablet smells horrible and my dog wouldn't touch it, unlike heartguard which he thinks is a treat. I attempted to break the tablet into small pieces and hide it in a piece of lunch meat but he still smelled it and refused to eat it. I then crushed it up and mixed it with peanut butter (which he loves) and that seemed to do the trick. If the manufacturer would just make it more palatable to dogs this would be the perfect solution. I was a little nervous after reading some reviews on here but my dog showed no abnormal symptoms after taking the medication.

            Comments about Trifexis for Dogs:

            My 3 dogs didn't like the taste or smell of the tablet. I used meat to mask the taste/smell. I did have to break the tablet as they are a little big for our Cockers.
            This is their first treatment, they did seem to itch a lot but I assume that was the med working.
            The itching has subsided, will continue using Trifexis.
