I agree.... I've posted several responses here pointing out the same thing. There are plenty of medications people take that can have rare but serious side effects. That doesn't mean they are pulled from the market so we can suffer with the issue the medicine would have addressed.
We have a Shiba Inu that's been on Trifexis for years. My dog is healthy and parasite free. We have friends with two Shiba Inu's, both take Trifexis, both are healthy and parasite free.
The sad thing is no one ever posts when the drug is working great. They only post horror stories when something goes wrong. That's human nature. Few people go online to share good reviews. Most only post a review when they have something bad to say. So all you see online are the 0.00001%.
