Lost female dog, Linden Street, Greenfield - reddish brown and skittish

She is a reddish brown color and slipped out of the gate, while our other dog - who is blind, minutes after we got her home from the rescue. She is a rescue from a puppy mill, so she is very skidish when comes to humans. She is fond of other dogs, so they may be helpful in getting her to come up. My other dog is just not able to navigate the woods and railroad tracks given his condition. She is very fast, will run if I try to approach her. The recuse said that she is typically food motivated, but that has yet to prevail in attracting her close enough to retrieve.
