We were driving on I-290 W from Chicago on our way to Naperville and found a female dog, running on the median just before the Austin Blvd (23A) exit.
She did not have a collar, no microchip and weighs approx. 20 lbs. She seems to be between 2-4 years in age and brown in color.
We are fostering her at our home in Chicago until the owners are found.
