How do you get rid of hiccups?

How do Dogs get rid of hiccups so quickly while most humans seem to struggle?

• My dog is laying here on the couch and I noticed she just contracted hiccups and within 3 hiccups was back to normal again. Its not the first time I noticed, just the first time I noticed while browsing Quora. Humans will go to the ends of the earth trying every homeopathic cure known or suggested and can struggle for a considerable length of time to rid themselves of them. IME, nothing works 100% of the time and yet I have seen my dog clear them quickly every single time. This is not to say she gets them frequently, nor do I but I have had them for hours at a time in the past. (She is a Shar-Pei, not that I believe that is relevant)

  The answer is in our anatomy.. our epiglottis is perpendicular to the axis of the trachea and is almost vertical due to our upright pose while it is slightly tilted in case of dogs!
