Why Do Dogs Get Hiccups When Sleeping?

If your adult dog or puppy seems to hiccup when asleep, you might be curious why this happens.

Why does your dog get hiccups when sleeping, and should you be at all worried about it?

Don’t worry.

By the time you have read this post, you will know everything you need to know, including if you need to take a trip to the vet or not.

Why Do Dogs Hiccup When They Are Asleep?

Dogs get hiccups when they are sleeping for the same reason they get them when they are awake.

Hiccups are caused by fast, intense, and repetitive contractions of the diaphragm.

This can be caused by indigestion, stress, and in some cases, a medical condition.

Hiccups happen when your dog has involuntary contractions of its diaphragm.

They can be caused by indigestion, eating too fast, not chewing food before swallowing, stress, gastrointestinal issues, or kennel cough.

There is no specific reason they get hiccups when sleeping, but they are most likely to get them during the REM (rapid eye movement) sleep phase.

Just as in humans, the REM sleep phase is the deepest phase of sleeping for your dog.

They will be deeply relaxed and breathing deeply and slowly, which might be why they are more likely to hiccup.

What Are Hiccups?

Puppy and adult dog hiccups are caused by the diaphragm’s fast and intense contraction.

The diaphragm is a muscle that separates the stomach area from the chest and lungs.

The diaphragm’s job is to allow the dog to breathe by expanding and contracting the lungs and rib cage.

Usually, the diaphragm moves smoothly and regularly, but when hiccups occur, it spasms, which creates the movement and noises we associate with hiccupping.
