At the beginning of the 20th century, the English Toy Terrier was one of the most popular toy dogs in Russia.  However, in the period 1920 – 1950 the breeding of pure toy terriers was almost stopped and the number of dogs fell to a critical level.  Only in the mid-fifties did Russian dog-breeders begin the revival of the breed.  Practically all dogs which were used for breeding had no pedigrees; many of them were not pure blood.  The Standard drafted for Toy Terriers significantly differed from that of the English Toy Terrier in many aspects.  From this moment, the evolution of the breed in Russia went its own way.
On the 12th of October, 1958 two smooth-haired dogs, one of which had slightly longer hair, gave birth to a male dog with a spectacular fringes on ears and limbs.  It was decided to keep this feature.

The male was mated with a female which also  had slightly long hair.  Thus the longhaired variety of the Russian Toy appeared.  It was called Moscow Longhaired Toy Terrier. 

A dog breeder from Moscow, Yevgueniya Fominichna Zharova, played an important role in the creation of this breed variant.

It was during a long period of development, in an  isolated context,  along with  a specifically conducted  selection that a new breed was created  : the Russian Toy  with two varieties: Longhaired and smooth-haired.
