DRUG-SNIFFING DOGS – Two disputes involving drug-sniffing dogs will be heard by the court on Halloween. In one, the question is whether a dog brought to the front door of a home to sniff for marijuana amounts to a search. In the other, the court will consider a dog’s reliability and qualifications as a drug-sniffing animal in a case involving a traffic stop and a warrantless search that found the ingredients for making methamphetamines in a pickup truck.
