  I just use one of those flat plastic storage things that slide under the bed.  It is about 4 feet long I think and wide enough for Bailey to lay sideways in it.  It is big enough to put a heating pad in one side and the momma still has plenty of room to lay if she doesnt want to lay on the heating pad.  When the pups eyes open and they are starting to get around I use a pen like Ladyhawk has and line the bottom with a shower curtain and then blankets.  |
