I have a great pyrenees puppy that is 10 wks old. He lives here on the farm with our other dogs and gets some of his puppy food, but eats kibble with the other dogs too. But he burps constantly, and gets the hiccups really easily. Any idea what it may be? He seems to feel fine, no vomiting or diarrhea, good appetite, just burpy. Maybe he just needs some yogurt.
