I've heard nothing but good things about it in person. I only hear the horror stories online. What's the deal?

Also, if your vet thought you were crazy because you think there must be some connection between your dogs' symptoms and Sentinel, maybe you need a new vet. If your dogs were experiencing those symptoms RIGHT AFTER they took Sentinel, TWICE, there is a very good chance that Sentinel is the reason for their symptoms. They may be allergic to an ingredient in it, the chemical composition of the medication may not agree with them, etc. My diet, exercise, and general schedule is rather stable ... If I were to take some new medication, all of a sudden develop terrible rashes when taking the medication, but my doctor told me "There's no way it's the medication!" I'd be gone.

There have been many people who's dogs did great on the Trifeixs and then dropped dead no joke! There have been several deathly sick dogs on here who the only thing that could be found to be the cause was Trifexis. It is not safe and it is not worth the risk to have your dog on Trifexis and I would beg your friends to stop using it. All you have to do is google it to see all the terrible warnings and stories.
