The Black Russian Terrier must be strong of body and mind to perform its duties as a reliable guard and military dog. This is a large-boned and well-muscled dog, capable of pulling a heavy load, yet having the agility to traverse rocky terrain or overtake an adversary. The head and neck are powerful. A reliable, intelligent temperament is essential in a dog that also has strong protective instincts; courage is also a must. The weatherproof outercoat repels water while the undercoat insulates the dog from the cold. Length of coat should vary from 1.5 inches to 4 inches with longer coats detracting from the dog’s working ability.

Calm, confident and courageous sums up the Black Russian Terrier. Reserved with strangers, BRTs are very attached to and protective of their family. They are fast learners, but also independent thinkers, and they can be stubborn if pushed to do something they don’t want to do. BRTs are affectionate and social. They tend to stick close to their people, even inside the house. They are gentle and playful with children. They may not be good with strange or dominant dogs, but are fine with other pets and smaller canine housemates.
