Black Russian Terrier

Dog

The Black Russian Terrier, abbreviated as BRT, or Stalin's dog (Sobaka Stalina) is a breed of dog, developed to serve as guard dog and police dog. It is rare outside the countries of the former Soviet Union but beginning to be formally recognized elsewhere: in July 2004, for instance, it became one of the AKC's recognized breeds due to the efforts of Trident Kennels now located in Oregon.
