The Borzoi, also called the Russian Wolfhound and brought to Russia from Middle-Asian countries. Having medium-length and slightly curly hair, it is similar in shape to Greyhounds, and is a member of the sighthound family. The system by which Russians over the ages named their sighthounds was a series of descriptive terms, not actual names. Thus the word borzoi on its own just stands for "fast" in old Russian. Their fur is silky and flat, and wavy or slightly curly. The Borzoi is a quiet but athletic and independent dog. Most Borzoi are almost silent, barking only very rarely. They do not have strong territorial drives and cannot be relied on to raise the alarm upon sighting a human intruder. They are gentle and highly sensitive dogs with a natural respect for humans, and as adults they are decorative couch potatoes with remarkably gracious house-manners.
