This young lady (finally) was imported from Moscow & is a Black Russian Terrier. With this large beed, accepted by the AKC in 2004, is bred to be a guard dog, Please buy from a breeder you can talk to and see if needed. This is an important lesson I have learned. they are large & powerful and temprament, socialization and exerience and obedience training is not optional. They are wonderful dogs, very loving and funny but if bonded to closely with one person, can isolate you from your friends & family.
I sound like I don't like her BUT, I definitely love her like crazy. She is just a special breed.
