What causes a dog’s bloated belly?

A dog’s bloated belly can be caused by diet issues, such as eating too much or too many beans. Eating a large amount at once greatly burdens digestion and lets food pile up undigested in the gut. In that case, fast the dog for a day and give some pet probiotics to aid digestion.

Also, if a dog eats a lot of beans, the bacteria in the gut produce various gases as they break the beans down, causing gas bloat. Bloating can also come from diseases like ascites or gastric torsion, so if symptoms don’t ease, take the dog to a vet.
