It is best not to house your dwarf hamster with another hamster, especially the male species. They will bitterly attack each other. Both genders are not very friendly with other hamsters, and tend to be extremely territorial.
Well obviously they are much different in size but the smaller dwarves can actually live longer, they also breed much more rapidly.
Chinese hamsters have tails and dwarf hamsters don't and Chinese hamsters can live together.
yes
no
2 to 3 years
Dwarf hamsters tend to nip more and can live with multiple hamsters in a cage.
Syrian hamster - 2-3 years Dwarf - 1-2 years
yes but it is very diffcult and you would need expert experience if not then you are really lucky
No!!!! They will fight till one of them is severely injured or dead.
It is better that they do not. All hamster breeds are territorial and may fight.
Unless the dwarf hamster was in the same litter, I would advise against it. If they are not in the same litter, and you'd like to see if they get along, first put them in a neutral cage. Otherwise the hamster may feel that another male is trying to take over its territory.
There is a Syrian hamster (often going under the name of fancy, golden, teddy bear etc, all of these are wrong, pet shops just give them fancy names to make them sound better so people will pay more). They are solitary and the biggest kind of pet hamster. The next are dwarf hamsters. They are significantly smaller, and there are 3 different kinds. Chinese dwarf hamster. These are the smallest and have a longer tail than any other pet hamster kind. They can be kept in pairs, but fighting is a very high chance and your better off leaving them alone. The Campbells Russian Dwarf hamster. About double the size of a Chinese dwarf. They can live in pairs or groups. Winter whites: Very similar to a Russian dwarf, but slightly smaller, and has a different head shape. None can be cross bred other than a Russian Dwarf and a Winter White, but very unadvisable to do so as if done wrong, the hamster can experience extreme pain. Also the cross breeds (sometimes known as "pudding" hamsters) are prone to get more health problems, one being diabetes.
