In December, the Washington Association of Prosecuting Attorneys told officers in a guidance memo that dogs that alert on pot face limitations when a search warrant is sought but those are "not fatal to a determination of probable cause."The group instructed officers to point out that the dog was trained to smell pot and how that is relevant to other information when they seek a warrant, and that a "narcotics-trained canine's alert will still be relevant to the probable cause equation."In Pierce County, however, prosecutor Mark Lindquist said authorities are being cautious about the new law because judges might excise the dog sniff from their analysis of probable cause. He's also not convinced dogs can be re-trained. "We'll need new dogs to alert on substances that are illegal," he said.
