Location: Rocky Mountain Region, North America.

Dog breed: Blue Heeler Cattledog. Female.

Summary: Described by locals as Mad, Bad and dangerous to know. Owner, designated caretaker and dog walker describe the dog as "Aloof, but devouringly affectionate to a select few". Note, caretakers and owner have been observed speaking with glazed eyes as they talk of the need to "Serve the Princess" followed by mutterings of "We obey".

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.
