paper to outside housetraining 17 week old mini wirehaired dachshund

hi,

i am the daytime babysitter for a 17 week old male mini wirehaired dachshund.

he is partially paper trained- will mostly go on the paper, but not always.

we are trying to transition him to potty outside. sometimes he pees outside, never poops- sometimes he'll pee on the paper after a lengthy time outside of me encouraging him to get 'busy-busy"

the owner doesnt like to confine him, so has run of the whole house when she's home, and partially retricted to the living room and kitchen when he's alone and when i'm there (7am-6pm).

he was partially crated trained but the owner decided not to continue. he was pretty keyed up about being left alone in the crate and had some accidents in it. i am trying to teach him to like a different crate(plastic not metal, smaller) and he is so far sleeping in it during the day with door open and during training sessions he enthusiastically goes in and lets me shut the door.

should we continue to use the papers? if we do, should we reinforce that or not?

i have taught him sit, down, rollover, whisper, wait, off, leave it, give- all using the clicker training i've picked up on this website - so i know he can learn.

any suggestions would be greatly welcome

many thanks-i am a huge fan of clickertraining!jen
