Unfortunately, there isn’t a one size fits all solution to stop your Boston Terrier from passing gas. Digestive issues are a common problem amongst this breed.  However, you can start with avoiding possible culprits like grains, beans, and soy.  Smaller meals can also help your Boston Terrier absorb and metabolize their food better, thus also helping prevent flatulence.  Last but not least, focus on making sure your Boston Terrier doesn’t eat or drink too fast. When they do, they’re gulping air down more which can cause gas.
