Trifexis Skin Issues?

[Rand0mH3RO]

I was wondering if anyone else out there has had any issues with Trifexis. My 7 and a half month old German Shepherd was on Confortis and then was switched to Trifexis. Since he was around 4 months old he has been itchy. It has gotten progressively worse as time has gone on. He has gotten so itchy he has scratched himself raw and has had a rash of sorts. We thought it was a food allergy and have switched food many times. He is currently on Acana Pacific, all fish. It has no helped at all. Last month he was on antibiotics, topical steroids and antihistamines because he had scratched so much it was infected. During this time he was better most likely due to the antihistamines. BUT I have just had the revelation that he may be allergic to the Trifexis. I searched around on the forums but couldn't find any recent posts or discussions on the topic.

I'm currently in the middle of finding a new vet since I have lost complete faith in his original vet. The only solution she gave was trying to get him to be put on Hill's Science diet which I refused to do. If anyone in the Raleigh, NC area has any suggestions for a good vet I would greatly appreciate it.

first off , science diet sucks lol... glad we can all agree. but anywho, nicco has been on both comfortis , ( when we first got him for a month) and is now on trifexus ( past 4-5 months ) we have not had any problems with it.... i did notice he was a little itchy when we first got him, but after i switched to a higher quality dog kibble, it stopped right away, and he has had no problems since then. hes on taste of the wild prarrie now, and he loves it btw. i would def get to a new vet you feel comfortable with, since i guess there is really no way for anyone here too know if your pups allergic to that particular med. , as i said, niccos been on it for months now with no ill effects.......

and also, i know trifexus will kill all fleas that bite, and keep him from gettin infested and such, but maybe he is allergic to the actuall bites? we had a cat once that was SEVERELY allergic to flea bites, im talking within a month of being bitten, he would pull all his **** hair out and look like someone had shaved him from neck too tail tip..... maybe your dog is gettin bit a few times and having a reaction to that, not any medication or food? just pinging ideas.....

The special formulated vet science diet foods have their place. They ARE designed to deal with special problems in dog health.
It's just too easy to write off something because many of us associate SD with bad food.
My thoughts -- try it. You could at the same time get rid of the med that you are suspicious of. If the dog improves drastically, then introduce one or the other (either regular food you were feeding or Trifexis) and see what happens.
