Gilligan went missing on January 28, between 8:45 am � 9:45 am, near Splitrail Court and Mansfield-Webb Road in Arlington TX, near the Mansfield TX line. The high winds blew open our gate and he went wondering out. He is a Lab/Border Collie mix. He is black with white markings on his face, chest, tip of his tail and tips of his paws. His wearing a red canvas collar with christmas lights on it. He was wearing a tag but it fell off but I do have it. He is probably one of the sweetest dogs we have ever know and will be your best friend.
