The FourthAmendment.com Blog highlights a recent EDCA court ruling that found that because "Cody" appeared to be a "sophisticated" rather than "unsophisticated" canine dog, his positive alert to drugs on currency should be given significant weight in the probable cause analysis. See United States v. Approximately $77,000.00 in United States Currency, 2012 U.S. Dist. LEXIS 50404 (E.D. Cal. April 10, 2012). Here's a portion of the court's decision cited in the blog:
The Ninth Circuit has given probative weight to positive alerts by "sophisticated" dogs - dogs that react only to ephemeral by-product of narcotics and not to commonly circulated currency - to show that currency is substantially connected to illegal drug activity. See United States v. $42,500 in U.S. Currency, 283 F.3d [977,] at 982; United States v. $22,474 in U.S. Currency, 246 F.3d at 1216. . . .
As explained above however, where a canine is trained not to alert to currency in general circulation, but instead the canine alerts only to the by product of illegal narcotics, that evidence is to be afforded greater weight in a determination of this kind.
It thus appears that Cody's training lends itself to a finding that Cody is in fact a "sophisticated" dog. Therefore, Cody's alert to the presence of illegal drugs on the currency found in Claimant's vehicle is strong evidence going to the determination of whether the Government had met its burden.
