Does your dog throw up often when taking Trifexis? I was considering making the switch, but my parents dogs both have had a really hard time with it. Eventually they (my parents) gave up on Trifexis and went back to topical stuff because the vomiting was so bad.
To that end, I wouldn't mind maybe an accompanying table to the OP's medical list that maybe listed the negative side effects of some of these treatments. Might be a bit too much to ask though.
