It's just as difficult for us as it is for them, especially if you have to take them out on a leash like I do!
Mine wear coats, and they learn quickly to speed it up when it gets good and cold. They hate the snow, so we have to clear out a patch for them, and they can't get back inside fast enough.
I have a 4 month old male that is pretty much housetrained, as long as I don't let time get away from me and take him out on a regular basis. We're up to about every 2 - 2 1/2 hours now. We got him at 10 weeks and we took him out hourly at the start. We use a crate, too, but he's trustworthy enough now that he runs loose all the time while we're watching him. He will hold it until we take him out.
Gracie was 5 months when we got her, and her previous owners hadn't been able to housetrain her at all, but I truly think they just didn't try. We had her housetrained in two weeks.
I don't like the pee pads either, so that's never been an option for me.
The two young ones are crated at night, and they are fine until I get up in the a.m. They're usually crated from about 10:30 p.m. until 6 or 7 a.m.
They aren't any harder to housetrain than any other breed, but they are more sensitive to the cold, so I can understand your concern.
