A Russian dwarf is a type of hamster. It is quite small. They can bite but it is not a casual thing. They don't bite unless you do something they don't like i have 2 hamsters. I have 1 girl and 1 boy my girl is called Daisy and my boy is called Monty they are both Russian dwarf hamster and very cute ,healthy and well behaved. My girl is pregnant and they usually have about 10-13 babies. You have to keep the babies for 6 weeks. Just before the babies have been born you need to split up the father. keep the mother and all of the babies together.

yes you can clean a dwarf hamster.... its possible to do ... all you need is a fine haired brush and a bar of anti-bacterial hamster cleaner and give a good scrub.
If you have a dwarf hamster that you believe has a broken pelvis, you need to take it to a vet. The vet will X-ray it and determine the proper care it will need.

Well, in the summer my hamster had babies. When I got her she wasn't pregnant. Like a day later she was pregnant. I would say about two - three weeks... I think. If you need any more info check out hamsterific.com. If anyone would like to improve my answer, FEEL FREE!!!
Only a veterinarian can evaluate the situation, take your hamster as soon as possible.
You just need to train him. Robos are very wild so it may take a while to get him tame. My robos had babies and I trained the babies from birth so they were a little more calm.
