Has Gizmo gone poop yet today? What type of food is Gizmo eating? Gas is pretty normal for a Bulldog, they are famously known for burping and tooting their stinky horns. Lol. My 2 always get going when they are in the car with us, and then you just want to gag, roll down the windows and hang your head out for air. We get it times 2 , it's gotten a lot better since we switched to the Fromms Beef Frittata, their gas is much less than before, and their pops don't smell as much either. Don't get me wrong it still smells, it is poop after all lol. Just not as bad. My vet told me and actually showed me on one of Dozers' X-rays when he swallowed a sock, that Bulldogs have a gas bag or sac in their stomachs which causes them to fart. It looks like a shadow of a round bubble on the X-ray, it's about the size of a small child's fist.
