How long does it take for a dog’s bloating to ease?

There is no fixed time for a dog’s bloating to ease. After bloating appears, the owner can fast the dog for half a day and take steps to help expel gas, such as giving some pet probiotics and gently massaging the abdomen, plus light exercise to aid gut movement and release gas. Dogs that eat too fast easily swallow air and bloat, so feed measured meals on a schedule to build good eating habits.
