Sudden Bloating In Dogs. Bloat generally occurs when food or gas stretches the dog’s stomach. Any growth inside tommy’s stomach could cause the bloating you see.

Pay attention to areas that feel hardened versus the areas that are soft and malleable. In severe cases, this bloated stomach can actually twist on. Hot food, cold food, big kibble, little kibble, too much food, too much exercise, too many carbohydrates, and stress have all been touted as causes of bloat, but remain.
