A year and a half ago, Hwang applied to an agency for funding for research using sniffer dogs, but was rejected. Besides those of Weily and the student training him, her expenses have been graciously defrayed by benefactors and other research funding sources.
黃美秀曾在一年半前向有關單位申請偵測犬研究計畫，但被打回票，目前除了威利，也在訓練威利的弟弟（老爸 Baxter 因故到機場服務），花費都是靠善心人士及其他研究經費挹注。
