The borzoi , also called the Russian wolfhound , is a breed of domestic dog (Canis lupus familiaris). Descended from dogs brought to Russia from central Asian countries, it is similar in shape to a greyhound, and is also 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. Borzói is the masculine singular form of an archaic Russian adjective that means “fast”. Borzáya sobáka (“fast dog”) is the basic term used by Russians, though sobáka is usually dropped. The name psovaya derived from the word psovina, which means “wavy, silky coat”, just as hortaya (as in hortaya borzaya) means shorthaired. In Russian today the breed we know as the borzoi is officially known as russkaya psovaya borzaya. Other Russian sighthound breeds are stepnaya borzaya (from the steppe), called stepnoi; and krimskaya borzaya (from the Crimea), called krimskoi.
