cold trailing
n.— «Cecil soon called out, and a beagle was eliminated. The canine’s sin? Barking too much before the chase—”cold trailing” in the parlance of the trialers. Cecil wanted a chase before culling dogs from the cast.» —“Handlers test beagles’ zeal at field trials” in Mebane, North Carolina Columbia Tribune (Columbia, Missouri) Dec. 23, 2007.
