Borzoi

The borzoi is a breed of domestic dog (Canis lupus familiaris) also called the Russian  wolfhound and 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 the word "sobáka" is usually dropped. The name "Psovaya" derived from the word Psovina, meaning "wavy, silky coat", just as "Hortaya" (as in Hortaya Borzaya) means shorthaired. In Russia today the breed we know as borzoi is therefore officially called "Russkaya Psovaya Borzaya". Other Russian sighthound breeds are "Stepnaya Borzaya" (from the steppe), called "Stepnoi";
and "Krimskaya Borzaya" (from the Crimea), called "Krimskoi". In Russian criminal lingo the word borzoi means "insolent".

The plural "borzois" may be found in dictionaries. However, the Borzoi Club of America asserts "borzoi" is the preferred form for both singular and plural (in Russian, the plural is actually "borzýe"). At least one manual of grammatical style rules that the breed name should not be capitalized except at the beginning of a sentence; again, breed fanciers usually differ, and capitalize it wherever found.
