Hiccups...

Sometimes, Luna abruptly gets hiccups while sleeping.

Ever since I was a child, my family always has dogs, a sheltie, a husky, and two Pomeranians. But for me, this is the first time to raise a puppy from very early puppy hood. So, I've never seen that a puppy has hiccups, which made me surprised at first and still makes me worried at times.
