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.
No Syrian hamsters are very Territorial and they like to live on there own but dwarf hamsters like to live in groups or pairs otherwise they would get too lonely.

It depends on weather it's a mean hamster or not. Hamsters are usually better without other hamsters in the same cage. A mean hamster may kill or hurt another hamster if that other hamster has a lot of the human scent on it. If the human scent gets on a baby hamster, the parents will eat it.
I'm not quite sure, but dwarf hamsters types can tolerate other hamsters. Fancy black bears, I assume aren't in that category, so they must be pretty territorial.
