black dog syndrome

(名詞) 黑狗症候群:在動物收容所中,黑狗或深色狗不受青睞,而淺色狗較易被領養的現象。

The Humane Educational Society will do its part to fight "black dog syndrome" with an adopt-athon this weekend at PetSmart, 2130 Gunbarrel Road. According to HES officials, big, black dogs often are the last to be adopted from animal shelters, a phenomenon known as black dog syndrome.
