Attached File: See above photo.

Location: Rocky Mountain Region, North America.

Dog breed: Australian Shepherd. Female

Summary: Has a personality best described as 'Viking Beserker'. Known for devastating the local population of squirrels. US postal carriers report the need to carry Milkbone bribes to avoid the fate of missing FedEx delivery vans and drivers. Aussie Shepherd has a bewitching hold over owners and dog caretakers who seem to adore her above all else. Malachite carvings with suspected infected Geas have been observed in that household.

Recommendations: Continued covert surveillance despite difficulties due to the region being under the authority of the US Government's Black Chamber which has not been cooperative with our agencies.
