Got pup in frigid weather,
-20, -30 the first few weeks. HEAVY snow.
Because we have had problems with Italian Greyhounds sneaking off to pee to avoid the cold, we decided to train our ACDx to use newspaper in extra bathroom.
He's 100%--pees and poops in there. Never anywhere else in the house or his crate.

He's out all morning doing chores (7:30-Noon),and he comes inside and zooms to the bathroom.
We put him outside in the morning right as he gets out of his crate, he will go outside then, when he's desperate to go. He knows the command" go pee" and I reward ("good pee" and treat) every random outdoor pee I see.
It's not much of a problem when we are at the farm, but it IS a
a problem when we leave -- he tries to hold it until we return. We went to a herding thing 3 hrs away and over an entire day (left at 6;45, returned about 8:30pm) he only peed once. He will pee in any bathroom with newspapers on the floor on command(he's been in the famous Minneapolis airport bathroom) but, when visiting, not everyone is keen on this.... He does not like newspaper outside...he likes his newspapers not moving in wind! He seems uncomfortable being in "doggy areas" such as road side Rest Areas with dog poo or the dog area outside puppy class ..His peeing is not inhibited by being on a leash, but by where he is.
I am thinking that more and more time outside will naturally change him over but it does not seem to be working very quickly.
Suggestions?

How old is he?

My puppy only did the business in our back yard for months. Then, when she was about 10 months old, we went on a road trip (Denver to Taos, NM). She wouldn't go when on the leash. I thought she would burst. The first night was horrible. She finally peed after at least 7 hours. We kept taking her out (no sleep for us that night). The next morning, the innkeeper told us there was a dog run. Heaven!!!

Anyhow, she is much more flexible now that she is a year old. So, maybe with age, your dog will start going outside.

Our first pup came to us in the middle of winter, too. Never got past newspapers in the garage. I refuse to go through that again.

I bought Ed's e-book, Common Sense House Training for our new pup (soon to be born). He states in the book that a dog that pees/poops in the house is not house trained. I have a feeling he'd suggest following his protocol from scratch. It will take longer than it would have if you'd followed it initially, but you and the pup will probably be happier in the long run.

Just my opinion. Good luck.

I had to paper train my dog when she was young.

To break he habit I waited to take a week off from work, then we went back to house training 101. I just didn't allow her access to the room where the papers were. She's now house trained to where she will no go in he house no mater what.

One time I caught her sneaking back into the room where the papers were. I scolded her, and brought her outside. Shre never did it again

I don't think it will be that hard. At least he already has an idea of one specific place to go. Some people who paper train have the papers on every open spot of floor in their house!

Thanks for suggestions!
I do not want to extinguish the behavior totally. At 7 mos he is completely reliable inside with the mudroom bathroom. I guess I'd like to enlarge his pee-poop repetoire
to include elimination on command in strange locations outdoors,to be used when travelling/going to training. Can that be done, or over time will the "pee in bathroom" generalize to the pee anywhere inside, leaving a dog who is in fact NOT housebroke?

I suppose anything's possible. But it seems confusing to me--and confusion is the opposite of training.

The message it seems to send is that eliminating in the house is okay (or even preferred?!)--but only sometimes, in a specific kind of room, on newspapers.

But you've already found out that creating that environment for the dog isn't always possible when you aren't in your own home.

IMO, learning housetraining is very situational and specific for most dogs. My young dogs had a difficult enough time transferring pooping in their own yard to pooping on any other patch of earth when we were travelling. They did figure it out--but they didn't automatically make that generalization in their mind.

So I think trying to set up TWO different scenarios for your dog for elimination (and one of them only happens occasionally) will be difficult. And I try to have as little "difficult" as possible when it comes to pee and poop. Why create unnecessary anxiety over something that is a natural function that must happen several times a day?

If it were my dog, I'd start over and housebreak him in the normal way. Outdoors is the only place where pee and poop are allowed. Period.

I agree with Tracy. Its hard enough wih them developing their own preferences. Then to distinguish between outside is ok, and then inside is ok, but in only one place. It just seems too confusing.

Spring is almost here, why not just teach him outside is the place to go? He might hold it for what seems like forever, but he will get used to he new routine. If you need to you can always go back to the indoor spot next winter.

We had problems with my dog holding it because of the snow. All of a sudden there was no grass, and she didn't know what to do. Finally, she decided that climbing on top of a snowbank was the best place to do her business!

One day the snow melted and she held it ALL day. FInally, at 11:00 pm she decided to give a patch of dirt in front of the house a try.

Now she has developed a preference for the park. She holds it while we walk for a mile to get there!

As long as it is not inside we are good.

Thanks for tips, we'll move to outdoors only.

Using advice (and some GREAT WEATHER) we have 24 hrs of outdoor elimination only.
He's on the way, thanks.

Having been there/done that, and was not successful because of my ignorance, I suggest keeping the pup tethered to you or in its crate at all times in the house. You don't want to give it a chance to "fail".

Great weather, yes, definitely a wonderful thing.
