Well, that is kinda my problem too, afraid they might choke, that is why I let my hubby do it most of the time. He has lots of training and has done it way more times than I have, but even I have done it successfully with both cats and dogs. None of our animals have choked to death yet and have taken their meds whether they wanted to or not
But, you don't put it down so far that you can't see it, just make sure you close their mouth quickly hold their head up in the verticle direction and blow down their nose and stroke their throat before they have time to think about it and work the pill back up to the front of their mouth
We used the additional technique with the oral syringe water squirt with our last collie to give her meds when she would no longer eat on her own.
The method with giving a couple of blank treats first and then the pill hidden treat works for us too.
Sometimes when you have given a pill in a treat and they have figured it out, you just have to try a different method and don't use the same technique each time.
