Cow's pilling sessions twice a day had been eventful. If I do not use the vertical carrier trick, I would have a small bite mark to show after each session.
Even with the carrier trick, he could still spit the pill out. Nevertheless, I've reached Round 8 this evening and I did it this round without the carrier! And no, he also did not bite me!
He recovered very quickly the next day, as predicted by the vet. Apparently, when prescribed the correct antibiotics, it works very fast.
Tomorrow morning will be Round 9 - the Finale and then, I'm home free!
Wish me luck, please.
