HELP IN CATCHING LOST DOG

SORRY TO ASK THIS but if anyone can help...Bo Bo the airedale has been spotted and is being chased.  I am headed there but am about an hour away at work.  She is on the west side of the DuPage River, and is being chased north from 135th Street.  If someone could start at 127th Street and go south along the river, that would be wonderful.  Thank you so much to anyone who can help.
