A dog named Ruach has touched many on social media after his owner shared the pup's challenging and unusual story on TikTok.

A clip posted on Wednesday has gone viral showing how difficult, and sleep-filled, Ruach's life is on the TikTok account ruachthenarcodobbie.

The pooch's rare and curious condition? Narcolepsy.

In the video, the Doberman tries to go on a walk with his owners and their other dog. The emphasis is on "tries."

Ruach has narcolepsy, a neurological disorder in which sufferers are subject to sudden attacks of sleep.

This means that Ruach can fall asleep at the drop of a hat – or in his case, while walking.

And that's exactly what happens to the Doberman several times in the viral clip.

Just a few seconds into the walk, the poor pooch gets "too excited," according to his owner, then collapses on his leash. His owner then wakes him up, and the bunch continue their walk. But just as the pup starts to run off again, he falls fast asleep once more.

The video has 1.5 million views and counting, and is aptly titled: "Trying to walk a dog with narcolepsy."

The clip has awakened many TikTok users' curiosity and raised questions. Ruach's owner answered some in subsequent videos and followed up in the comments.

Before the Doberman's owners knew he had a health condition, they thought the young puppy was simply "sleepy and clumsy."

But his case worsened, so his owners took him to a cardiologist to find out if something was wrong with his heart. There they ruled out a heart defect.

Then Ruach's owners took him to a neurologist.

"At that point, we decided to look into narcolepsy," the owner explained in another TikTok video.

Eventually, the rescue pup was diagnosed with the "rare genetic disease" that's considered an "autoimmune disorder," according to his owner. He suffers from nap attacks most often when he gets too excited, or "plays real hard."

After seeing the viral video, many users wanted to know if the dog's condition could be cured or if the puppy would grow out of it.

"He unfortunately won't grow out of it," his owner responded of the five-month-old puppy, "but they say it may decrease as he ages."

Hopefully, Ruach's condition will become less disturbing to his daily doggy activities as he gets older.
