Chin tumbled down the stairs!

[Buddy]

My chin ran out of my room under my feet, as I went to catch her she shot down the stairs (obviously going way to fast) she started rolling and tumbling down the stairs the second tumble I think she squealed a little. When she finally landed at the bottom of the stairs she sat and waited for me to pick her up. I can't see any blood and I can't see an obvious pain or injuries. But I did see her landing on her back as she was rolling and her head. What do I do if she has a head injury? And what would be the obvious signs of them both? She is running she is jumping... She was a little shaken up, I guess...:bump1:

Watch her the next few days. Be sure she is eating, drinking and pooping normally. Be sure she is walking and acting normally. If not take her to the vet.
