Hi. About a year ago, my 9 year old husky/shepherd/wolf mutt regularly started having big burps that smell like sulfur. Sometimes farts, too. He had a sensitive stomach when young...I tried several different foods, and he has eaten Canidae for the last 7 years. Perfect, since I developed celiac disease 3 yrs ago and Canidae is gluten-free! He keeps my kitchen floor very clean, occasionally has plain popcorn thrown his way, and "picks" his own blueberries when we hike- otherwise no people food. He doesn't have vomitting or diarrhea.
Soooo....could his digestive system just be changing as he reaches "geriatrics"? Could he have a parasite (all his bloodwork, stool tests, etc are normal)? Should I try another food, or is there something like "gas-x" for dogs? Do you think it uncomfortable for him? Could my dog have GERD?
All I know, is if it tastes half as bad as it smells, then he would love to try any ideas you have!
