My experience has been if they stupidly have it bubblegum flavor they'll let it run out the side of their mouth. A firm hold and getting it to the throat area makes it impossible for them to do that but that requires two people. Over the years my success with pills has been better. Hold them down, pry mouth open, shove it into back of the mouth then hold mouth shut over nose so they have to swallow. Clever ones can trick you with pill pockets like dogs you mentioned which I mentioned in your comment about dogs doing that.🤭
