It very much depends on what agency the dog is/was working for. TSA or border customs agents would be conducting their inspections inside secured locations; they’re very unlikely to need an attack dog, but they do need a very highly trained dog to detect all manner of illicit shit.
the k-9 unit in your local home town police? they’re trained as generalists, with much lower training in any specific task. As such, they won’t have as broad of a detection capability as say a dedicated drug sniffing dog, or as skilled at tracking as, say, a cadaver dog, or be as useful in pursuits as, say, a patrol dog. But they’ll be capable in all of the roles and come with a significant advantage in that they’re fast to deploy because most will have dogs on duty around the clock, and virtually every agency has one in house.
