Beagles will hunt what you teach them, right now at the miami Airport they are use to detect ,fruits and vegetables in the luggages of arrival flights from other countries, they can also detect bombs and drugs.
I had one that would run anything you set her on, wounded deers, squirrels and she would tree and stayed tree or follow the squirrels by site,she would also love to chase rabbits.

There is a State Law Enforcement agency that uses one, which they drive around neighborhoods with the beagle's head sticking out the window, if she smells chemicals used in crack home labs she will let you know, LOL
