A Russkiy Toy will often require veterinarian assistance in changing from its puppy teeth to its adult set.

Active and cheerful, the Russkiy Toy was originally bred both as an anti-rat dog and a watch dog.

The Russkiy Toy was bred as a rat fighter and as a watchdog originally, and can still exhibit the vocalisation expected from the latter.

By the 1990s, the long haired type of Russkiy Toy had hit critical numbers, but luckily a resurgence occurred due to a new generation of dog breeders.

The Russian Russkiy Toy is another similar dog, developed in Russia from early imports of the English Toy Terrier.

After the fall of the Iron Curtain, a number of foreign small breed dogs were imported, and this caused the popularity of the Russkiy Toy to decline.

There are two types, smooth haired/coated and long haired, which were known by a variety of different names until brought together under the same standard as the Russkiy Toy in 2000.

The Russkiy Toy (also commonly called the Russian Toy) is a very small breed of dog originally bred in isolation in Russia from the English Toy Terrier.

As with most breeds of dog, the Russkiy Toy can suffer from patellar luxation, which is where the knee cap slips out of place when the knee bends as the groove that normally holds it in place is too shallow.
