Hiccups in dogs are generally similar to hiccups in humans. Hiccups cause a ‘hic’ sound in humans, following a spasm of the diaphragm, whereas hiccup symptoms in dogs include the ‘hic’ sound, spasm, and the occasional burp.
However, dog hiccups can sometimes manifest in the form of a soundless spasm.
Hiccups in dogs are normal. Although there are rare cases when hiccups can be dangerous to your dog’s health, hiccups are generally nothing to worry about. Hiccups tend to look slightly more dramatic in dogs than they do in humans.
You will be able to see your dog’s chest vibrate vigorously when your dog has hiccups. Hiccups in dogs look worse than they are. Some dog owners may confuse coughing, reverse sneezing, regurgitation, and seizures as hiccups.
To avoid being confused between those conditions and hiccups, you should look out for differentiating features. When dogs cough, they open their mouths to release air. Dog coughs are usually much louder than hiccups. When your dog regurgitates, they will expel food from their mouths.
Seizures and hiccups look similar in the sense that both tend to result in a rhythmic rise and fall of your dog’s chest. However, seizures and hiccups differ in terms of one important aspect. Hiccups can occur even when your dog is asleep whereas seizures can only occur when your dog is awake.
Most hiccups last for merely a few minutes. However, if your dog’s hiccups occur frequently, last for longer than an hour, and are observed with symptoms that are not typically associated with hiccups then your dog’s hiccups become a cause for worry.
