We switched from Simparica to Vectra 3D. Simparica seemed to give him tummy upset (not uncommon for him) and lethargy. Vectra 3D I haven’t noticed that, but he seems like he’s trying to itch his back (no redness) and after two days he has a strong woody smell along his back where applied. I’m reading that the Vectra3D has very strong meds & the more you google the more scared you get reading that flea & tick meds can have fatal side effects. Can I get an opinion on both?
