Russian Dwarf Hamster refers to two species of hamster. The Winter White and the Campbell’s Dwarf Hamster. These two appear similar to each other and are often confused. Breeders all over the world have bred many different attractively colored hamsters. These are called ‘fancy hamster.’ Most “Russian Dwarf” Hamsters available to buy from pet shops are Hybrid Dwarf Hamsters.
