Don't get a dwarf, they are horrible pet rabbits.
Experienced rabbit owners wouldn't even reccomend them to other experienced owners.
If you want a good first rabbit get a Lop, they are a great breed, very docile and generally a great first rabbit.
Please look at your local shelter first too, there are so many bunnies that are in shelters. Realise they live as long as dogs too and they need to be spayed/netured or your going to have a nasty rabbit that you won't be able to touch and the risk of cancer.

The floor time is MINIMUM 2 hours a day.
If you can only commit to that though don't get one.
It's not fair to let them out only 2 hours a day.

If you want a animal that is moody, can be nasty, not like to cuddle, chew things, hard to catch then by all means go for it.
They can be great pets but they are hard work and you need to be commited to them.

Also if your not going to be commited to feeding lots and lots of veggies then you might want to re think getting one too.
Their diets should be veggies,fruit and hay only (more so veggies than fruit). Some people seem to think pellets are good for them but to each their own I guess.

Oh another thing, they can't live on shavings and new paper causes their feet to turn green. Wire cages give them abcesses on their feet unless they have a big peice of carpet to get away from the wire.
