If your new puppy is of Russian dog breed it is quite natural to give a Russian dog name to him or her.
The Caucasian Mountain dog, the Circassian Orloff Wolfhound, the Black Russian terrier, several breeds of Laïka, the Samoyed, and many more breeds began in Russia, and it would carry on tradition to name these companions with Russian dog names as their ancestry would suggest.
Many of the breeds which hail from Russia are large and very furry. This helped the animal maintain warmth during the harsh, long winters where they evolved.
