I cannot believe they cannot catch Nikko! He must be very tired and hungry by now. Poor boy. Hopefully, someone can entice him with food and bring him in soon. Maybe try contacting Jacki Hadra with IMOM. She may be able to offer additional suggestions no one has thought of. I know she lured a stray Dalmatian (Luv Bug) in once.
