The Black Russian Terrier is a large, immensely powerful worker of heavy bone and coarse all-black coat. BRTs are known for their courage, confidence, and intelligence. Bred to guard and protect, they are naturally aloof with strangers. What's the word we're looking for? Imposing? Massive? Majestic? How about just plain 'big.' This brawny guard dog of the Siberian steppes can tip the scales at 140 pounds and stand as high as 30 inches at the shoulder. They're much taller when the huge, brick-shaped head is considered. The tousled, all-black coat is warm enough to allow BRTs to patrol some of the coldest habitable places on earth. The old expression 'He moves well for a big guy' applies to this nimble-footed giant.
