Trifexis is bad stuff for Masumi. Poor thing, because her reaction to it wasn’t immediate, it took a while to make the connection. The first two times she had a response we dashed off to San Francisco Veterinary Specialists. They couldn’t determine what she had gotten into but we all surmised that it was cannabis.
Jump forward several months and her reaction to the medication was almost immediate, finally making it clear that she shouldn’t be on this form of flea medication.
