Why do dogs get hiccups?
Well, there are a lot of reasons. For example, a dog will get the hiccups when he or she gulps food or drinks water too fast. Excitement and stress can also be triggers. Also, if you’re a smoker and your dog stays inside a lot, that could be a cause.2
Dog hiccups can occur no matter what age a dog might be. But puppies tend to get them more than adults.
A likely reason is that puppies get excited more often than adult dogs because they have more energy. They also tend to be a little more energetic when it comes to eating. As a result, they will be more likely to inhale too much air at mealtime.3
Some experts believe that hiccups in a puppy happen due to an excess of gas in their system, or an upset tummy.4
