Today my pup was due for his monthly dose of Trifexis, a heart worm/intestinal worm/flea prevention pill. I gave it to him after his meal as usual and about an hour and a half later he vomited up his meal. The vets office his closed so I have no way of asking them at this moment. Do you think the pill had enough time to do its job or should I consult about getting him another dose? My "Bones" finished some antibiotics a week ago for some sort of gastrointestinal inflammation he had going on... I waited a few extra days than the vet recommended before giving his Trifexis. I think vomiting may be a side effect from the pill but I just want to make sure he will still be covered. Any advice?
