pottying in crate

Question
I have a 3 month old Doberman female.  I have a crate that I used for previous pets.  and they did urinate in the crate.  I cleaned it out and bleached it.  I don't know if this is the problem or not.  She can go outside and does.  I take her out at regular intervals.  at night I still get up every 3 hours to take her out.  I can come in from taking her out and 10 minutes later she can have an accident on the rug,  I can't let her out of my sight for even a couple of minutes.  If she is in the crate during the day even though she might have been out 30minutes to an hour before she will still go in the crate.  she doesn't always whine to be let out.  I started out putting something in the crate for her to lay on, but she would always make them wet.  So I stopped that, it seems that just leaving it bare seems the best.  Should I get a new crate that doesn't have a previous smell in it?  Should I wait for her to tell me to get out?  How do I now break her from urinating in her crate?  I have had Dobermans all of my life but usually used the paper training method and had a room that I could keep them in but in my current house everything is carpeted and have had to go to the crate system.  Please help.

Answer
I don't think a new crate will solve the problem.  It is only natural that a puppy resists its crate at first.  What the puppy
wants more than anything else is to be with others, you, anyone else in the
household, and any other pets.  In our modern society, even if we are home,
other things distract us from the attention an uncrated puppy must have.   The
only real solution is to crate the dog when you aren't around.  Leave it some toys.  Perhaps a Kong filled with peanut butter.  Don't leave anything in the crate the dog might chew up.  Rather than relaxing and catching a nap in their den, some puppies protest by fouling the crate, or it could be stress.  I haven't had this problem.  I do see many questions suggesting it, and saw my daughter fight the problem.  

A wire grid in the bottom of the crate will help keep the puppy up out of urine and to a lessor extent stools.  They are available with the crates, but expensive and hard to find.  A piece of closely spaced wire closet shelving from a home supply place is cheaper.  This reduces the mess, making the protest much less effective.  My rack fell apart after many puppies.  I used a vegetable bin with holes drilled in it at first with my now 5 month old Holly.  Here is a link to a picture of her in it, http://www.photolocker.net/images/Labman/hollyhighanddry.jpg  The longer haired the puppy, the higher it needs to be.  In warmer weather, you can just haul the crate out and hose everything off.
