Most dogs don’t chew, but I’ve heard many people think gulping the food contributes. My dogs burp when they eat too fast, so I tend to think air would/should come back up, not go all the way through. You can add water to slow them down and have them swallow less air, or you can pour the food on a cookie sheet so they have to pick it up one piece at a time. Yes, fresh fennel works the same, don’t over do it.
