It is my understanding that they should have just enough room in the crate to lay down comfortably. If they can get up and walk in it, then it is too big. You can put a box in half of it...if it is too big...this way...she cant pee/poop in one part of it, and then lay down in another part of it (as to avoid laying in their own mess).

I have to say, though, Dale (my now 9 month old puppy)(who is potty trained, by the way), peed in his crate somewhat often as a young pup. I had a blanket in there, and i think when he peed on it, it absorbed into the blanket, and he didnt even realize he was laying in it...although, Swissies, are very hard to house train, due to the size of their bladder (which remains rather small for some time), compared to the amount of fluid they can take in (huge amount)...they just cant hold it sometimes.

So, i understand the frustration. Although, Dale only ever peep, not pooped. ONe thing that did work well, is make a schedule of when they eat, drink, crate, etc.,as soon as you let them out of the crate, let her out to potty, and before she goes in, let her out to potty. I had a book that layed out a schedule for me, and in time it worked...

So, the only thing i suggest, and i am no expert, as i only have one dog, is to just make sure that there isnt so much room inthe crate, for her to do her business in one part, and they lay in another part...then it is too big...good luck...
