My dog is shaking beautifully :)

Scratched, said goodbye, dusted themselves off :)
We saw him shaking coolly, a wave went straight from head to tail, I never cease to notice small details that plunge me into an inexplicable state!
No Seriously, have you ever watched any phenomenon for at least 5 minutes? How strong was your concentration?
Write in the comments what you observed unusual or beautiful the other day!
