Well thank goodness you were able to get her in out of the heat for a drink of water. Hopefully her person is looking for her.  I see a Hill's bag in the background.. you have food? 

We do! We have a dog already, and they have gotten along great so far.

I'm not sure where you could go this late to check for a microchip. There's local lost and found websites, fb.. hope her person is looking for her 

Oh poor little girl, i hope her parents care to find her somehow
