Today (12/29) we found a small  female dog running loose on Peralta.  No collar.  We took her to Petsmart to be scanned for a microchip and there was not one.  She is black with a very distinct white mark on her.  Very friendly and well behaved.  Vet said she is approximately one year old and very healthy.  I believe she just got loose from her yard/house.  We cannot keep this dog.  If we cannot find the owner, we will find a good home for her.  If this is your dog you will need to identify the white mark.
