Yes, dogs do get hiccups. Hiccups in dogs are caused by spasms in the diaphragm, the muscle that separates the chest from the abdomen and plays a vital role in breathing. These spasms result in an involuntary and uncoordinated breath accompanied by the characteristic "hic-cup" sound. Dog hiccups can happen after eating or drinking too quickly, when they are excited, stressed, tired, or cold. Puppies are more prone to hiccups than adult dogs, and certain breeds with shorter faces, like Bulldogs and Pugs, are also more susceptible. Generally, hiccups in dogs are harmless and tend to go away on their own within a few minutes. However, persistent hiccups could indicate underlying health issues requiring veterinary attention.
