PROVIDENCE, R.I. (AP) - More colleges are getting bomb-sniffing dogs in a time of always-looming security threats, with two in New England among the latest. Black Labradors named Figaro and Bella attended the same training class and arrived in October at the University of Rhode Island and Worcester Polytechnic Institute in Massachusetts, respectively. Many colleges have used dogs for years to look for drugs. And while some larger schools have had explosive-detection dogs for a while, there has been an uptick in the past year or so, said David Bousquet, president-elect of the International Association of Campus Law Enforcement Administrators.
