My dog killed a butterfly

I was not there when it happened but according to my little sisters, a small white butterfly flew into the house at night and my dog,Ding Ding was chasing it and stopped when it was standing on the wall.Then she used her paw and smashed that poor butterfly!For some reason,I think it's very cute cause it was not expected at all but also sad for the innocent butterfly.

How can a dog so cute like her kill an innocent butterfly with her paw?!

P.S:I think Ding Ding looks way better when the hair in front of her face is short.Not many dogs can look good with short hair or maybe I'm just biased.Hahaha!
