<human>: I have a medium sized dog, so big or small bites food are both acceptable.  He doesn't chew the small bites, he just swallows them whole and usually coughs a couple up after or during eating. So I bought him the large bites thinking maybe if they're bigger he'll want/need to chew them. He still didn't chew, and chokes them down and back up. So right now I have him back on small bites because if he's not going to chew either way, then at least if the bites are smaller he will be less likely to choke. He doesn't like the small bites though, but he needs them. Anyone deal with this before and come up with any solutions to get him to chew?

Thanks!

Can you condense the text into a few key points?
