Does anyone recognize this dog?

I found an older, female dog wandering around in traffic this evening on Marine Drive outside the Cocoanut Grove. She has no collar and was just wandering around lost. She willingly got into my car and is well behaved. I’m going to take her to the after hours microchip scanning station at the Humane Society to check for a microchip and if she doesn’t have a microchip I guess I can keep her in my garage over night. Thanks.
