My next dog [will] be a Papillon.
I am interested in [competing in breed-] conformation & agility... this would entail often being indoors only,
& possibly overnights in a hotel, Id like to have the dog trained to both grass (snow) & newspaper.
i'd be hesitant to use newspaper; it's too easy for dogs to generalize to the texture & appearance of paper,
which is ubiquitous in our homes & even in a hotel - accidents are too easy.
EX, the hotel slides the bill [or receipt] under the door, the dog's in a hurry & the single page doesn't hold
the urine / stool; not only is the copy ruined, but the carpet is damaged, & U are charged.
I've seen dogs who were paper-trained LEG-LIFT on the daily paper, or when it was out of reach, BELOW it -
on the upholstered chair, on the nearest rug / carpet, under the table where the paper is sitting to be read...
& i've also seen OWNERS who didn't comprehend what the dog was doing, who compounded the minor error
of voiding "below" or "nearest" the paper by punishing their poor dog, sometimes severely - which doesn't
magically erase the innocent mistake, remove the mess, or clean the carpet / chair, it only vents spleen. :nonod:
Now, their poor dog - who was earnestly trying to get as close as possible to that dam*ed paper! -- has no idea
WHAT to do, or WHERE to go. Thoroughly confusing the dog about what substrate is "correct" is a disaster.
I'd suggest either a dedicated litter-box with a clumping, flushable litter, or the gravel-bottomed litterbox
that is PLUMBED simply into one's own toilet
& flushes the waste, washing the gravel.
If U don't want to use litterboxes, i'd advocate pet-pads WITH a frame to secure them so they don't shift,
AND 'walls' or sides to confine the urine. Simply plopping a pad or 2 on the wall-to-wall is appealingly easy,
but it's way-too easy for the dog to overshoot the edge... backing up, standing with 2 feet on & 2 off,
etc, put the waste off the pad on the floor.
I know some breeders train [their pups to use] corn pellets, [the fuel used in] corn burning stoves,
& I could use that, if the puppy is already trained to it.
this would be much-better than paper - the pellets are distinctive in odor, texture, & appearance,
so no worries about confusing other substrates with a litterbox surface. :thumbup1:
Emphasis added in bold:
I would not do this with a larger dog, but Paps are toy[-sized].
We do not have stacks of newspapers in the house, so I am not worried about that.
i'm a bit confused - what aren't U worried about? :huh:
I have the impression - which may be wrong - that U meant to say U =Do= have stacks of newspaper,
IOW a ready, handy supply of paper-training materials, but for all the reasons i gave above & others
not listed, i'd avoid using newspapers.
If U DO use a fireplace, furnace, coal-stove, etc, consider rolling those newspapers into paper-logs to burn:
it requires a small mechanical roller, but they are tightly-rolled for slow, efficient combustion, & produce ash
that can safely be used on a garden, or as soil-amendment in landscaping.
Clean up of dog waste is a big problem in densely populated cities and I know some people use a newspaper
on the curb to make clean-up easier.
true, but i've used potty-pads for the same purpose, especially when a dog has DIARRHEA - which is awful
to try to pick-up with a conventional bag, but easy to confine & bundle-up for discarding, with a pad.
I've also used potty-pads or even paper-plates to 'catch' stools from animals that had intestinal parasites -
i've had the care of many neonates, orphans, & neglected animals over the years, & U cannot safely use
a bog-standard vermifuge or other TOXINS in nonhumans whose health is already compromised; kits,
pups, dogs or cats who are underage/ underweight / malnourished / elderly / fragile or massively infested
CAN * DIE if they are given the typical parasite-killers, which are lest we forget, poisons: they are meant
to kill the parasites, but can easily kill the poor, suffering host when that host is not healthy.
I've used minced raw garlic to evict [live!] parasites from nonhumans whose health was poorly - it's safe,
but U **cannot** let the contaminated feces hit the ground; then U're in for endless cycles of re-infestation,
if it's on Ur own property, or even worse, infesting other innocents who are exposed to contaminated soil
OFF of Ur own property, if U allowed such parasite-riddled feces to fall on curbside, park, or elsewhere
that is open to common use. Capturing it before it hits the ground is imperative.
I thought how easy it would be to do the same when we're out & about, or as I said, at a show.
Does anyone do both lawn & pad / paper?
I've taught many dogs to use a potty-pad [with a frame, or in emergencies, without - such as on an airport
concourse, or in the lady's room of a store, etc]; i've also taught dogs to use litterboxes, but my favorite is
the easiest option of all: the walk-in shower stall at home, OR the bath-tub, near the drain. :yesnod:
As an emergency back-up, it's perfect: if the pads in the frame are too wet, too dirty, or U are stuck
in traffic & the conventionally-housetrained dog cannot get outside to void, the shower or bath-tub is always there. 
For toy-sized dogs, if there's no walk-in shower, U'll need a stable, well-secured set of steps or a ramp
up to the tub's side-wall, & a safe way to get into the tub - so s/he doesn't slip or simply fall hard onto the
slippery, rigid surface. Stairs up & a ramp descending in, a ramp on the outside & a sloped fat cushion
as an interior ramp, a non-slip, easy-draining, thick mat to cushion the impact on the tub's floor, etc.
As an aside -
be sure to expose any puppy to every imaginable substrate, as early & often as possible: sand, bark,
macadam AKA asphalt, wet tall grass, short dead-dry grass [which may be sharp!], gravel, concrete, even
tile or sealed stone, just in case; it's always possible that Ur dog will be stuck somewhere & need to void on some
weird-feeling, odd-smelling, unabsorbent surface.
EX, perhaps U get sick on vacation -
Ur dog, now 2 or 3-YO, is temporarily in a boarding kennel, & has to void on the concrete of an I/O run,
whilst using an indoor area for sleep, meals, & shelter from the weather. WHAT IF s/he has never voided
on concrete, before?... Then there's a miserable period of crying or barking, hopeless waiting, painful pressure,
all delaying the inevitable: they've GOT to go. :nonod: But they DON'T have to be miserable or be so upset;
the poor dog is already coping with a strange environment & unavoidably, at least somewhat anxious.
Let's make sure that at the very least, s/he is already familiar with DOG RUN substrates, & will void confidently
on a concrete surface. 
Goof-proof Ur dog by exposing the pup to everything imaginable; every substrate, any setting - urban,
rural, livestock, open space & few humans, crowded streets & many humans, on-leash exercise with a front-clip
harness in a city-park, off-leash exercise [but safely away from cattle or game until they are proofed! ---
inside a fence or a walled pasture or garden, not simply let a young, untrained dog run free around
stock or game; it's not worth the risk of an all-too-exciting chance to chase, harass, or leap on some poor
beast, & then spend the next 4 to 6-months trying to RE-train the dog to be calm around non-dogs!...]
A well-reared puppy should be able to move from a 2,000-acre off-leash daily life on a Texas ranch
to a 100-square-foot studio-apartment in Manhattan, & not merely COPE, but thrive, within a 10-day or
fortnight transition. Change is inevitable, & we can't assume that what is true of today will be assuredly
just the same tomorrow - accident, divorce, illness, injury, financial disaster, any sudden upheaval can mean
an entirely-new sort of life for ourselves OR for our loved pets, & they should be prepared in advance.
It is unkind & unfair to teach our pups to live in or thrive in only ONE setting; they need flexibility to cope well.
